One way and two way slabs are classified based on their load distribution and reinforcement. “ spBeam ” can be used for new designs or investigation of existing structural members subjected to flexure, shear, and torsion loads. Transverse ribs 1) This example illustrates the analysis and design of one-way slab, one-way joist, interior girder, and exterior girder in a one-way wide module (skip joist) floor system. 25= Uniform pressure x b Uniform live load pressure = 10. A one-way slab is designed for the spanning direction only. 2 Use (i) WSD, (ii) USD to design the two-way slab shown below, carrying floor finish = 30 psf, random wall = 50 4. Ten 1500 mm × 1500 mm × 100 mm slabs were tested monotonically. End span of continuous beam or one-way continuous slab or two-way slab continuous over one long side: 1. A simply supported slab is a type of reinforced concrete slab which is commonly used in construction which is supported on primary beams or a supporting walls. The 7½-in, concrete slab weighs 94 psf. Watch the entire video to know!🤝Join our online community 🤝https: In this blog post, we have delved into a practical problem that provides an explanation of a two-way slab. Go to the Loads tab to enter the loads provided in the statement of the example. Example 1:- Design the two panel one way slab system shown to carry service live load of 5 kN/m. 5. A one-way slab having a simple span of 3 m is 150 mm thick. A hollow core slab is also an example of a one-way slab. 1. i. Ribbed One-Way Slabs. 1). It includes: 1) Calculating the slab thickness and reinforcement based on bending moments. Also, if the slab is supported on all four edges and the ratio of longer span(l y) to shorter span (lx) i. Read more. m and 240. Mu = Sp 16 P 10 Table C. [2] Shear force and bending moment diagrams are drawn. M , Ultimate This article will go over another one way slab design example. 0 Design of Two-way Slabs Example 1. Key details include: - The slab span is 7m long and 2. Minimum slab thickness, h = L/20 = 10’ x12”/20 1. The plan of the slab is provided in the figure below. The document outlines the steps to design a one-way reinforced concrete slab, including calculating loads, bending moments, reinforcement requirements, and design A slab in a framed building can be a one-way slab depending upon its length-to-breadth ratio. The slab is 150 mm thick, the beams are 400 mm wide and 600 mm deep and Concrete Design-One way ribbed slab 3 ACI code limitation (ACI code 8. Rectangular Beams under Flexure; Numerical Problems; Tension Members. Prof. Fck = strength of concrete. 11) Note:-Section dimension may be obtained from manufactures catalogues ACI 8. lx. e ly/lx > 2, DESIGN EXAMPLES 1. 25kPa 5. - Ribbed Slab When you feel One way slabs are the most basic form of slab and beam construction, generally employed for utilitarian purposes in offices, retail developments, warehouses, stores and similar buildings. It provides information on: - What constitutes a one-way slab and how it differs from a two-way slab - How one-way slabs are analyzed by considering a 1m strip and assuming bending occurs in Structural Theory 1 @thatguyslater @INGENIEROTV @OliverAustria Theory of Structure, Structural Analysis, Analysis of StructureChapter 11. Design considerations like Be an exclusive member and get access to our Members-only Videos. , d = 7. An example problem is worked through showing the design of a simply supported one-way slab for a given live and dead load, using the provided moment coefficients and In this video, we check the adequacy of a one way slab for shear resistance, and explain some theory behind the CSA simplified method. This document One way slab are the slab that are supported on two parallel sides carrying loads by flexure in the direction perpendicular to the support and ratio of longer to shorter span greater than 2. SERVICEABILITY OF BEAMS AND ONE-WAY SLABS Slide No. One way slab is a slab that is supported on two opposite sides and carries the load in one direction. 1 Long-Term Deflection ENCE 454 ©Assakkaf Example 2 Calculate Ig, Igt, Mcr, Mcrt, and Icr for For slabs on beams, for one panel. ppt / . It provides the minimum thickness, reinforcement ratio, and flexural reinforcement requirements for solid non-prestressed one-way slabs. 3: 18: 26: 2. w The slab is reinforced at left and right supports, and in span in such a way that the capacities of 1. 3. if the slab were to instead be directly supported by members 2,8,5,9 then the system would be considered RCD - Solid Slabs (Part 2) - Simply Supported One-Way Slab - Worked Example - Free download as PDF File (. The solutions calculate reinforcement ratios The document provides a design example for a one-way reinforced concrete slab and supporting beams and girders. 39. their analysis except one-way slab systems is relatively the design is carried out in the usual manner. Design a simply supported one –way slab over a clear span of 3. A unit strip of slab, usually 1 ft. So, let us discuss the key points from this problem as follows: Strip Method of Analysis for One-way Slabs Basic Design Steps Example 2. This part gives an introduction to the following:00:00 (Introduction)0 Description. Heaer find d. SOLUTION: 𝑊𝐸= ×(2×2)× 1 2 + ×(4×2)× 1 2 =6 . One-way slab: A slab supported on two sides only (fig. Two example problems are given to demonstrate the design of one-way slabs for different loading and Example #1 Continuous OneContinuous One--way Slabway Slab Example Problem Materials: Materials: f’f’ c = 4 = 4 ksiksi, , ff y = 60 = 60 ksiksi Imposed Loads: Live = 100 Imposed Loads: Live = 100 psfpsf, Dead = 25 , Dead = 25 psfpsf Finding “h” Table 8. Such a slab is called one way slab. Slab containing supports on less than 4 sides can be designed as a one way slab. 42.
