Job No. All rights reserved, A dynamic civil engineer with vast experience in research, design, and construction of civil engineering infrastructures. To check the shear capacity of slabs, the shear stress (vEd = VEd/bd) must be checked against the shear capacity of an unreinforced section (VRc,d). By. The main steel is placed nearest to the surface to give the greatest effective depth. A plate is a flat structural element that has a thickness that is small compared with the lateral dimensions. Beams 25 5. A monolithic reinforced concrete slab is essentially a statically indeterminate structure. However, in addition to self weight consisting of all permanent loads, live loads have to be added. 3 Unbonded and external tendons 1. This spreadsheet performs an analysis and design of two-way spanning reinforced concrete slab. Therefore, the main reinforcements will lie parallel to the short span, and that is where you check your deflections (see why short spans are critical in floor slabs). Rating: 12 Description. For slabs with irregular plan shapes and slabs subject to a combination of point loads and distributed loads, Johansen’s yield line analysis and the Hillerborg strip method provide powerful methods for strength calculations. (e) Crack ControlAccording to Clause 9.3.1.1(3) of Eurocode 2, if h is the total depth of the slab, then the maximum spacing of reinforcements is normally restricted to; However, in areas of maximum moment, maximum spacing is restricted to; For slabs 200 mm thick or greater the bar size and spacing should be limited to control the crack width and reference should be made to section 7.3.3 of the Eurocode 2.

Linkedin. Design the floor slab below. FULL version: R.C. Continuous beams may be provided in one direction or two orthogonal directions, to support slabs that may be solid or ribbed in cross-section. It is necessary to point out that the critical span in the analysis of solid slabs is the short span. It is further stated that in monolithic construction, where partial fixity occurs along an edge of a slab but is not taken into account, the top reinforcement should be capable of resisting at least 25 percent of the maximum moment in the adjacent span and this reinforcement should extend at least 0.2 times the length of the adjacent span measured from the face of the support. The service live load is 100 psf and 4000 psi concrete is specified for use with steel with a yield stress equal to 60000 psi.

And also input point loads. For a slab of a given shape and support conditions, the distribution of shear forces, bending, and twisting moments in the slab due to externally applied loads cannot be determined easily. Section Civil & Geotechnical Engineering 1 Calc. Support Conditions, b). The general arrangement of the floor plan of a building is shown below. This is actually an expensive operation (see cost of fixing reinforcement in Nigeria). Furthermore, if the longer side of a slab panel exceeds twice the shorter side, the slab is generally designed as a one-way slab, but that does not mean that the slab is transmitting load in one direction only. In normal cases, a strip of slab 1 m wide is checked against span-to-effective depth ratios. Design the slab following the provisions of … the building width × column spacing, exceeds 30 m2. (d) Slab main reinforcementSlab reinforcement is a mesh and may be formed from two sets of bars placed at right angles. The coefficients can be obtained from Table 3.14 of BS 8110-1:1997. You will receive a link and will create a new password via email. usually one and two-way spanning slabs • Punching shear –e.g. Columns 33 6. This will on the one hand, help the control of cracking, increase durability, while on the other assist placing and compaction. Replies. Plan View of Floor System Assume partitions will not be damaged by deflections. Simply supported two-way slabsWhere the corners of slabs are free to lift and no provision is made to resist forces at the corners, the maximum moments per unit width are given by the following expressions:Msx = bending moment in strips with span lx = Msx = αsxqlx2Msy = bending moment in strips with span ly = Msy = αsyqlx2where lx is the shorter span of the panel, ly is the longer span of the panel and q is the design ultimate load per unit area. It can be used by both practicing Engineers and students. Eurocode 2 is one of the most globally recognized structural design authorities in the world today.The worked example below give detailed steps use in slab design to EC2. They are; Generally, for rectangular slabs with standard edge conditions and subject to uniformly distributed loads, normally the bending moments are obtained using tabulated coefficients. Depending on the boundary condition and the properties of the slabs, methods of finding bending moment is expressed in the BS 8110 Part 01 as follows. Terms* (100ρ1 fck)1/3, k = 1 + √(200/d) = 1 + √(200/119) = 2.296 > 2.0, therefore, k = 2, ρ1 = As/bd = 452/(1000 × 119) = 0.003798 < 0.02; K1 = 0.15. A beam is similar to a slab in so many ways but there are fundamental differences in behaviour and stress distribution of the two elements.

Design Two-Way Continuous Solid Slab. Difference between one-way and two-way slabs. The design presented here is just an excerpt from my final year project ‘Structural Analysis and Design of 35,000 Capacity Reinforced Concrete Stadium’. Design Example of Reinforced Concrete Two-Way Solid Slabs using BS8110 Code (Part 2) - (Continuous Restrained Two-way Slab). In detailing, if a slab is assumed to be simply supported at an end support, it is advisable to provide reinforcement for a probable negative bending moment due to the monolithic construction of beams and slabs (Reynolds and Steedman, 2005). For two way slabs, the precise amount and distribution of the load taken by each support, and consequently the magnitude of the bending moments on the slab, are not easily calculated if assumptions resembling real conditions are made. When a slab is supported on all four sides and the ratio of long span to short span is equal or greater than two, it will be considered as one way slab. The value of K depends on the structural configuration of the member and relates the basic span/depth ratio of reinforced concrete members. Continuity across a beam is treated as fixed support. 1.1(a)], in which the structural action is essentially one-way, the loads being carried in direction perpendicular to the supporting beams or walls. Job No. In this article, I will discuss One way slab design procedure with example. Description: This is an R.C. The method applicable in any particular case depends on the shape of the slab panel, the conditions of restraint at the supports and the type of load. Thanks.
