SIMPLE SPAN REINFORCED CONCRETE SLAB BRIDGE INPUT: VERSION 6.2 VERSION 6.2 Fill out the fields as appropriate based on the information in the plans. There are two acceptable methods to design concrete: the working stress method and the ultimate strength method. Working Stress Design is called Alternate Design Method by NSCP (National Structural Code of the Philippines) and ACI (American Concrete Institute, ACI).. Code Reference NSCP 2010, Section 424: Alternate Design Method ACI 318M-99, Appendix A: Alternate Design Method Notation f c = allowable compressive stress of concrete f s = allowable tesnile stress of steel reinforcement Working Stress Design. A civil engineer must know all the aspects regarding the flat floor system. Civil Engineering Design (1) 10 Dr. C. Caprani 2. ACI 360R-10 “Guide to the Design of Slabs-on-Ground” 2. Ultimate limit state design theory. Reinforced concrete may be the most important material available for construction. A similar approach was also used by Kemp6 to determine the yield criterion for an orthogonally reinforced slab. One-way Slabs; Two-way Slabs; Staircases.

Prof. Dr. Qaisar Ali CE-320 Reinforced Concrete Design-I Introduction In reinforced concrete construction, slabs are used to provide flat, useful surfaces. Especially, computations have been made by use of BS 8110 based spreadsheets; publication produced by the Reinforced Concrete Council (RCC) as part of its project 'Spreadsheets for concrete design to … Bending will take place in the two directions in a dish-like form. Flat slab system is an important division of concrete floor system. A finite element model may be created to analyse a complicated loading arrangement. “How to design concrete structures using Eurocode 2”, The Concrete Centre, 2010) - Figure 2: Simplified detailing rules for slabs 15.0 PRESTRESSED MEMBERS AND STRUCTURES 22 With the combined experience of Slabtech management, we offer a one-stop solution in a project life cycle to our clients. I have a two storey building, and my second floor and roof loads are transmitted to column footings below my slab on grade. ACI 360, "Design of Slabs-on-Grade", refers to this as a Type B slab. Effective width of flanged beam. Inroduction When the ratio (L/S) is less than 2.0, slab is called two-way slab, as shown in the fig. Types and Design of Staircases; Compression Members. In March 2020, we hosted a webinar, “Case Study : Reinforced Concrete Solid Slab Bridge" by Mak Guo Shao, Bridge Engineer. This section contains information on how to design reinforced concrete elements of a structure. Here, we have tried to gather various reading materials available in the web about flat slab floor system in one place. 4. Design reinforced concrete flat slabs for punching shear at internal, edge and corner columns by specifying the distance from the support to the slab edge; the program automatically determines the shear perimeters. 1. A reinforced concrete slab is a broad, flat plate, usually horizontal, with top and bottom surfaces parallel or nearly so. The Robot offers two possibilities for a design of RC structure members: calculation of the required (theoretical) reinforcement area needed for the RC member generation of the provided (real) reinforcement for the RC member REINFORCED FLAT SLAB DESIGN EXCEL SHEET. 3. You can also enter the amount of longitudinal reinforcement (that affects the shear capacity) in the two main directions.
