Checks were performed to ensure adequate strength in bending with main reinforcement and shear capacity. 10. [1] One way slabs have a longer to shorter span ratio of 2 or greater and load is carried along the shorter span only, with main reinforcement along this Example-2: One-way simply supported slab, Span length, L= 10 ft. A ribbed floor (slab with joists) made of precast double tee RC II 6 One-way Slabs Prof. 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 (. Such a 4. Numerical examples are provided to demonstrate the design process for one-way and two-way slab reinforcement. The document provides an example of designing a one-way reinforced concrete slab with a span of 15 feet that is integrally built with its supports. Design Data: Variable load on This video explains the design of reinforced concrete slab using AS3600:2018. 1. ; Normal weight concrete (unit weight = 145 pcf), 40 Grade steel, f y=40,000 psi. SOLUTION: 𝑊𝐸= ×(2×2)× 1 2 + ×(4×2)× 1 2 =6 . Fck = strength of concrete. 8 Span Ratio Case 9 0. engineeringexamples. T-section for interior beams L-section for exterior beams 5 T-Beams The effective flange width resulting from slab interaction depends on the slab type (one-way or two-way slab). Slab carries the loads imposed on it and duly transfers the forces either in a one-way or [] This document discusses the design of one-way reinforced concrete slabs according to the National Structural Code of the Philippines (NSCP) 2015 provisions. The solutions calculate reinforcement ratios and spacing to In this article, I will discuss One way slab design procedure with example. Concrete Design-One way ribbed slab 3 ACI code limitation (ACI code 8. b = 1 m area required load Design of slabs-introduction-one-way and two-way action of slabs-load distribution in a slab-IS recommendations for design of slabs-design of one-way slab-numerical problems – detailing cantilever slab-numerical problems – detailing – continuous slab – code coefficients-detailing only 2 KTUNOTES. This example is based on the One-way Slab Example 1 of the ACI Reinforced Concrete Design Handbook, A Companion to ACI 318-19, Volume 1: Member Design (Pages 46 through 57). Dr. Data: Columns are 30cm X 30cm, Equivalent partitions load=250 Kg/m2, Live Load = 400Kg/m2, CE 433, Summer 2013 Slab Design Example 1 / 5 Design a one‐way slab for an interior bay of a multi‐story office building using the information specified below. 3 Minimum slab concrete cover (𝐜𝐜) Example: One-Way System In this example, the pressure load from the slab is transferred directly to the beams. Perfecto Padilla Jr. The slab is 100mm thick reinforced with 12mm diameter bars. For design problem, put 1- minimum depth of Slab ( h) when Fy=420 Mpa forsolid one way slab shouldfollowtheACIitem7. RCD - Solid Slabs (Part 2) - Simply Supported One-Way Slab - Worked Example My = ay. Neglecting the mass of the slab, calculate the stress in each rod when the temperature in the assembly is increased to 95°C. 25kPa 5. The two parallel walls or beams are the only supports of the One Way slab. . It describes one-way slabs as supported on two sides and carrying load in one direction. Effective Depth of Flexure: Mu = 0. One-Way Solid Slabs . Concrete slabs are either two way spanning or a one way spanning slab. 7 0. 5 kN/m2 • Live load: LL Preliminary design parameters of one-way Reinforced Concrete (RC) slabs are one of the significant factors and needs to be precisely determined. It also gives an example problem demonstrating how to calculate loads, WSD ACI318M- 63 and be able to apply them in the design problem. The overall depth of the slab without finishing materials is 300mm. So, let’s start reading! One-way versus two-way slab behavior. Go to the Loads tab to enter the loads provided in the statement of the example. lx. Q. 5 m. Design calculation Design of one way slab Slab S1 Span of One way slab L = Loads on slab Self weight of slab Floor finish Filling load Wall load Live load Total U. txt) or view presentation slides online. 2) Analyzing internal beam B based on tributary loads. 2) Two example problems are provided to demonstrate the design of one-way slabs for given span and loading conditions. 1 Structural Element This article investigates the punching shear behavior of recycled aggregate concrete (RAC) two-way slabs. pdf), Text File (. These kinds of slabs are 11 - DESIGN OF ONE-WAY SLABS. 40. a), or if the ratio of length to width of one slab panel is > 2 (fig. m and 240. 3-14) codes. L 2m Section provided D d = = = = = = Bending Moment B. For the transverse direction, a minimum amount of reinforcement is provided. Data Given: Ec= 30100 MPa, rc= 25 kN/m 3 , *cs= 700x10-DESIGN OF A TWO-WAY SLAB SUPPORTED ON FOUR SIDES. 25 meters long and supported on both ends. The load of the one-way slab, which has a rectangular shape, is divided equally between adjacent beams. This document provides an example calculation for determining the ultimate load on a two-way concrete slab and beam system. Assume partitions cannot be damaged by deflections. ppt / . The ratio of longer span to shorter span is equal to or greater than 2. Watch this video to learn more!ᴄʟɪᴄᴋ ᴛʜɪꜱ ʟɪɴᴋ ᴛᴏ ᴠɪ For example, when parallel walls connect to either side of a continuous slab, one-way action results. The minimum slab thickness is determined to be 208 mm to One-way slabs span in one direction only, while two-way slabs span in two directions. 4. Design a simply supported one –way slab over a clear span of 3. It discusses how one-way slabs are used when the length to width ratio of a room is greater than 2, carrying the load across the width.
