Baluster: Vertical member supporting the handrail in a railing. Reach him at ubani@structville.com. Wall load applied on the structures by different softwares. RCC Staircase Design. Thanks you so much. For example, they may be arranged in a straight run with a single flight between floors, or a series of flights without a change in direction. Staircase, thus, is a structure enclosing a stair. Generally, stairs are usually of the following types: Straight stairs are stairs along which there is no curvature or change in direction on any flight between two successive floors or levels. For beams, the bending moment and the shear forces are acquired. The staircase is a … Wind load: wind load is the distinct load on the structure due to the wind intensities. Flight: A series of steps extending from floor to floor, or from a floor to an intermediate landing or platform.Guard: Protective vertical barrier along edges of stairways, balconies, and floor openings.Landings (platforms): Used where turns are necessary or to break up long climbs. In this case, the waist or thinnest part of the stair construction need be no more than 60 mm thick say, the effective lever arm for resisting the bending moment being about half of the maximum thickness from the nose to the soffit, measured at right angles to the soffit. All of these results are required for the complete construction of the building. Staircase - mid-sized contemporary concrete u-shaped open staircase idea in London Glass floors connect the stairs to the kitchen-dining level at the top of the house, and to the living level below, to help light flood down into the entrance hall. Simple straight flights of stairs can span either transversely (i.e. There are different types of stairs with different configurations. Design the staircase by using concrete grade 25 and strength of reinforcement of 500 N/mm2. The structural idealisation of the staircase is shown below; Thickness of waist and landing = 200 mmDepth of riser = 150mmLoad actions on the stairsConcrete self weight (waist area) = 0.2 × 25 = 5 kN/m2 (normal to the inclination)Stepped area = 0.5 × 0.15 × 25 = 1.875 kN/m2 (global vertical direction)Finishes (say) = 1.2 kN/m2, We intend to apply all gravity loads purely in the global y-direction, therefore we convert the load at the waist of the stair from local to global direction by considering the angle of inclination of the flight area to the horizontal;𝛼 = tan−1(1.2/1.75) = 34.438989°Therefore the UDL from waist of the stair in the global direction is given by = (5 × cos 34.438989) = 4.124 kN/m2, Total dead load on flight area (gk) = 4.124 + 1.875 + 1.2 = 7.199 kN/mVariable load on staircase (qk) = 4 kN/m2The load on the flight area at ultimate limit state = 1.35gk + 1.5qkEd = 1.35(7.199) + 1.5(4) = 15.719 kN/m2, On the landing;gk = 5 + 1.2 = 6.2 kN/m2; qk = 4 kN/m2, The load on the landing at ultimate limit state = 1.35gk + 1.5qkn = 1.35(6.2) + 1.5(4) = 14.370 kN/m2. The stair diameter is used to determine the angle of rotation. A section of a staircase is shown above. Stair is simply a structural member that gives vertical access from one floor to another. Slab is given its thickness and the slab type is defined as membrane element which is used to represent only the inplane stiffness of members. What are the advantages of Prestressed Concrete over Conventional Reinforced Concrete? filled metal pan landing bp vb typical section metal pan landing e70xxelect x q r4.1 0 cew section a ref. The value of elastic modulus of materials, wherever required, maybe taken as per. The live load differs for different types of structure. As,min = 0.26 × fctm/fyk × b × d = 0.26 × 2.896/460 ×1000 ×169 = 276.631 mm2/mCheck if As,min < 0.0013 × b × d (219.7 mm2/m)Since, As,min = 276.631 mm2, the provided reinforcement is adequate. Detailing is provided in some softwares, where the rebars used should be defined. He is a member of the Nigerian Society of Engineers. Risers less than 100 mm and more than 200 mm high should not be used. Keep sharing our posts with others so that they can benefit too. The walls can either be of masonry or concrete (shear wall) depending on the loads coming on the building. The most comfortable height of riser is 175 mm. The seismic and the wind loads are employed by the software accordingly using the respective codes. Most of the softwares follow the same hierarchy of steps in designing. Reinforced Concrete Stairs Design Reinforced concrete stairs are the most common type of stairs used in all types of buildings. It displays results in graphical forms and also display real time-history displacements and generates reports. Practical Steps in Design of Concrete Buildings Concrete is arguably the most important building material which plays an important role in all building structures. However, when the width of a stairway exceeds 1800 mm, it is necessary to divide it using handrails. Treads should be at least 250 mm, exclusive of nosing. First, take the dimensions of the stairwell opening. The detailing components include concrete beams, columns and walls, steel framing, beam schedules, column schedules and connections. Stairway WidthThe width of a stairway depends on its purpose and the number of persons to be accommodated in peak hours or emergencies. The design of the main components of a staircase-stair, landing slabs and supporting beams or wall – are already covered in earlier lessons. The following can be used as guidelines; Step SizesRisers and treads generally are proportioned for comfort and to meet accessibility standards for the handicapped, although sometimes space considerations control or the desire to achieve a monumental effect, particularly for outside stairs of public buildings. The stairs are of the type shown in figure 8.20 spanning longitudinally and set into pockets in the two supporting beams. If you do the modelling right, then half the road is traveled. After designing, if some sections fail then you can do the interactive design and change the failed section and design again. The loads required for the building are defined here. In multi-storey buildings, ramps, elevators, escalators, and stairs are often used to facilitate vertical circulation. MIX DESIGN FOR CONCRETE STAIRS & STEPS Concrete mixtures for exterior stairways should meet the same performance requirements as those for other outdoor slabs: resistance to freezing and thawing and deicing chemicals (in cold climates), low permeability… 5.6 2 Determine material strength BS 8500-1: Table A.3 EN 206-1: Table F1 3 Select the waist, h and average thickness, t of staircase EN 1992-1-1: Table 7.4N EN 1992-1-2: Table 5.8 The typical nature of internal stresses induced in a simply supported straight flight stair and reinforcement pattern is as shown in the picture below. Dead load: This is the load on a structure owing to its self-weight. Tread: Horizontal face of a step. The effective span is 3 m and the rise of the stairs is 1.5 m with 260mm treads and 150 mm risers. In principle, the design requirements for beams and slabs apply also to staircases, but designers cannot be expected to determine the deflections likely to occur in the more complex stair types. Design Procedure Step Task Standard 1 Determine design life, Exposure class & Fire resistance EN 1990 Table 2.1 EN 1992-1-1: Table 4.1 EN 1992-1-2: Sec. For columns, the axial forces coming on it, the bending moment and the shear forces can be obtained. The spacing of column should be reduced considerably so that the load on column on each floor is less and the necessity of assigning large sections for columns is prevented. Nosing: Projection of a tread beyond the riser below. As compared to regular wooden stairs, concrete stairs are more durable and rigid, therefore it is a perfect choice if you want less problems for many years in a row. A series of winders form a circular or spiral stairway. Install Riser Forms. It is often stressed that any structure which is to be constructed should satisfy the need and efficiency with which it is intended and it should be durable for its desired life span. Structural design should be based on the sound application of fundamental principles of reinforced concrete design and a knowledgeable use of building codes and standards. Live load (impose load): This is the load on the structure due to moving weight (temporary loads). Some softwares allow users the ability to create specialized sections of any arbitrary shape and material, including rebar layout. This paper. The concrete was vibrated to minimize the bug holes. When spanning transversely, supports must be provided on both sides of the flight by either walls or stringer beams. As with the green book the scope of the Manualcovers the majority of concrete building structures and has now been extended to cover slender columns and prestressed concrete. Detailing of a shear wall from the software. Structural designing is a combination of knowing the behavior of structural members which are subjected to loads and designing them economically and aesthetically sound to give a safe serviceable structure. Design of a stair slab. The design of staircase, therefore, is the application of the designs of the different elements of the staircase. Riser: Vertical face of a step. The standard tread width can vary from 700 mm to 1300 mm and more, whereas the thickness of the concrete floating tread is from 60 mm to 100 or even 110 mm. Its virtue is its versatility which is its ability to be moulded to take any shape required for various structural forms. 1.3 Structural Design of stairs The theoretical procedures employed in the structural analysis of stairs is the concept of an idealised line structure and when detailing the reinforcement for the resulting stairs, additional bars should be included to limit the formation of cracks at the points of high stress concentration that inevitably occur. When initial discussions about the concrete spiral staircase began with the client, the objectives were to create a functional staircase that would take up as little space as possible, to open up the room to the 2nd floor for better air circulation to distribute heat more evenly through the home, and of course to create a one-of-a-kind piece of art to compliment the modern decor. It is also recommended that when an access height exceeds 600mm, a staircase should be provided. This structural design process has been carried out under use of BS8110 design code of practice. Design a straight flight staircase in a residential building that is supported on reinforced concrete walls 1.5 mapart (center-to-center) on both sides and carries a live load of 300 kg/m2. Curved stairs when viewed from above appear to follow a curve with two or more centres of curvature, such as an ellipse. Building interior concrete stairs is a complex project, as you have to build a formwork, install a structure of reinforcing bars, pour concrete and finish the stairs with a float. Ultimate shear force VEd = 35.358 kNv = VEd/bd = (35.358 × 1000)/(1000 × 169) = 0.209 N/mm2VRd,c = [CRd,ck(100ρ1fck)1/3] ≥ (Vmin), k = 1 + √(200/d) = 1 + √(200/169) = 2.087 > 2.0, therefore, k = 2Vmin = 0.035k1.5fck0.5 Vmin = 0.035 × 21.5 × 300.5 = 0.5422 N/mm2, ρ1 = As/bd = 753/(1000 × 169) = 0.0044556 < 0.02, VRd,c = [0.12 × 2(100 × 0.0044556 × 30)1/3] = 0.569 N.mm2Since VRd,c > VEd , no shear reinforcement is required. Structural requirements must be considered as well as confortability and the over all design. Here the final design is carried out as per the codes.

Nicolae Eugen E Fola. For public buildings of under 200 persons per floor, use a width of 1000 mm, for buildings between 200 – 400 persons per floor, use a width of 1500 mm. The loads which are defined and applied to the building are: Here the loads are applied on the sections and slab. The bending moments should be calculated from the ultimate load due to the total weight of the stairs and imposed load, measured on plan, combined with the horizontal span. They are used to change the direction of the stairs without landings. In modern architecture, stairs are designed to be aesthetically pleasing, and they contribute immensely to the interior beauty of a building. Stairs are important building elements that are used to provide vertical circulation and access across different floor levels in a building. After doing the structural analysis of the structure, it is designed to find out the steel used for the reinforcement for columns and beams.

Also, straight stairs may permit a change in direction at an immediate landing. No flight of stairs should contain less than three risers. On the Concrete Cantilever Stair Design we can use self supporting floating concrete treads. Selecting the proper boundary condition has an important role in structural analysis. winders - Winders are steps that are narrower on one side than the other. The stairs and landing are all supported by the beams along the short direction; no support along the long direction (flight of steps) The design moments for the stairs and landing may be determined by a simple static solution. Jul 7, 2020 - Explore Brian Fetter's board "Concrete staircase" on Pinterest. At Structville, we stop at nothing in giving you new dimensions to the profession of civil engineering. A spiral staircase has a 100mm smaller diameter than the given stairwell opening. The structure will be analyzed for the loads applied. Spiral stairs are similar to circular stairs except that the radius of curvature is small and the stairs may be supported by a column. A staircase can be made of reinforced concrete, steel, timber, and other composite construction materials. Stair consists of small series units known as steps. The deformed geometry of the building can be displayed based on any loads or any combination of loads, as well as animation of modes. Stresses produced by the longitudinal thrust are small and generally neglected in the design of simple systems. See more ideas about Concrete staircase, Staircase, Stairs design. TECHNIQUES OF STAIRCASE CONSTRUCTION Technical and Design Instructions for Stairs Made of Wood, Steel, Concrete, and Natural Stone. The standard width of any stair may be between 1.1 to 1.6 m. In public use building like malls, cinema, shopping center larger width of stair can be used. For each concrete step, cut a piece of 2x lumber to the width of the stairs and … Eg:Shear wall design is done according to IS 456:2000 but for that a command different from the usual, is given. Its height is generally taken as the vertical distance between treads. These components are reinforced with steel that give stability to the structure. READ PAPER. The modeling of support conditions at expansion joints and bearings needs a careful consideration of continuity of each translational and rotational component of displacement. Appreciate your effort and time to post this article. It is common to use simple supports (i.e. Your concrete steps will lie upon a subbase of granular fill, like open-grade stone, which will protect your poured concrete steps from shifts in the earth or deterioration. These concrete stairs are often precast in sections including landings or can be cast insitu for large or unusually shaped flights of stairs. Concrete is arguably the most important building material which plays an important role in all building structures. Construction of concrete stairs is a difficult task that requires an engineer to study all the aspects and design it and a skilled labour to construct it. It’s our duty to design a safe and serviceable structure and in order to do so we must predict the magnitudes of various loads that are likely to be applied to the structure over its lifetime. Design Stairs. In the design of stairs, account should be taken of the fact that there is always one less tread than riser per flight of stairs. When you start drawing the model, there are many options. Modification factor βs = 310/σs σs = (310fykAs,req)/(500As,prov) = (310 × 460 × 639.96)/(500 × 753) = 242.358 N/mm2βs = 310/242.358 = 1.2789Taking the distance between supports as the effective span, L = 4.35mThe allowable span/depth ratio = βs × 23.0258 = 1.2789 × 23.0358 = 29.460Actual deflection L/d = 4350/169 = 25.739Since 25.739 < 29.460, deflection is ok. Its width is usually taken as the horizontal distance between risers. Design of Reinforced Concrete (R.C.) The imposed load is 2.5 kN/m2and finishes is 0.5 N/m2. Columns should preferably be located near the corners of a building and at the intersection of beams. Design of Staircase Calculation – How to Calculate Rise and Tread Dimensions: While planning any stair important dimension to find out first that is rise and tread of stair and their numbers. The theoretical procedures employed in the structural analysis of stairs is the concept of an idealised line structure and when detailing the reinforcement for the resulting stairs, additional bars should be included to limit the formation of cracks at the points of high-stress concentration that inevitably occur. The entire process of structural planning and design requires not only imagination and conceptual thinking but also sound knowledge of practical aspects, such as recent design codes, ample experience and judgment. If the wall is not included then the frame loads are applied on the beams. Circular stairs when viewed from above appear to follow a circle with a single centre of curvature and large radius. Finite element methods may be used for the structural analysis of the entire staircase or two seperate parts may be Thank you very much.It was really helpful for me to clear ideas of staircase design with pictures. lapeyre stair 5/20/2014 per spec section a conc. The width of the staircase is 1160mm. Concrete stairs for commercial and residential projects Floating concrete staircase passed the structural test in 2011: Just now the new development, a self supporting concrete stair has been loaded with 350kg and has passed the test. These load combinations can be created by selecting the Indian code and also with the help of auto load combinations where they are generated by the software. Structural Engineers and uses the format of the green book (Manualfor BS 8110). Steps to Design a Spiral Staircase. Its virtue is its versatility which is its ability to be moulded to take any shape required for various structural forms. Various materials and finishes are on the table and the right combination of all of the options availabe makes a master piece design staircase.. (0.167). As the leading manufacturer of precast concrete steps in the U. S., Century Steps® provides the most innovative and durable concrete steps. We are expected to carry out a full structural analysis and design of the staircase according to EC2 using the following data; Density of concrete = 25 kN/m3; Compressive strength of concrete (fck) = 30 N/mm2; Yield strength of steel (fyk) = 460 N/mm2; Concrete cover = 25mm; Imposed load on staircase (qk) = 4 kN/m2 (category C3). The software takes the loads according to the code IS 456:2000 which is pre-installed in it. 1. © (2020) Structville Integrated Services Limited. When successive flights are at an angle to each other, (usually 90°), they are called angle stairs or quarter-turn stairs. STRUCTURAL DESIGN, DETAILING AND CONSTRUCTION OF REINFORCED CONCRETE STAIRCASES BY AYODELE AKIN-ADAMU LECTURE PRESENTATION ORGANIZED BY YOUNG CIVIL ENGINEERING FORUM (YCEF) MARCH, 2018 1 f ABSTRACT This technical material provides recommendations in the sizing of stair element, such as the rise, tread, maximum number of steps, minimum headroom and clearance… You can either draw it in the grid or use the template. a combination of the above-mentioned types. Staircase is one such important component in a RCC structure. For example, usually for a Residential Building the live load taken as 2 to 3 KN/m. Headroom Ample headroom should be provided not only to prevent tall people from injuring their heads but to give a feeling of spaciousness. Save my name, email, and website in this browser for the next time I comment. The risers are 16 cmand goings are 30 cm. Balustrade: A railing composed of balusters capped by a handrail. Construction of concrete stairs includes steps such as designing, preparing foundation, building formwork, placement of reinforcement steel bars, concreting, finishing and curing. The picture below shows a helical staircase. The basic steps involved are explained here in this article. Concrete design is performed as per IS 456:2000 and the steel design is done as per IS 800.
