In March 2020, we hosted a webinar, “Case Study : Reinforced Concrete Solid Slab Bridge" by Mak Guo Shao, Bridge Engineer. By the end of this course you will be able to do a full Reinforced concrete slab design and analysis with RAPT similar to what a professional engineer does. Accordingly, main reinforcement is required in the two directions. This course will limit discussion to normal reinforced structural concrete using 4,000 psi concrete and 60,000 psi rebar. Ultimate limit state design theory. a slab system consisting of approximately rectangular panels with the ratio of longer-to-shorter span within a panel not exceeding 2.0, per American (ACI 318) and Canadian (CSA A23.3) concrete codes. The ultimate stress method is the one most commonly used. Short Braced Axially Loaded Columns 2.1 Development The design of such columns is straightforward. I have a two storey building, and my second floor and roof loads are transmitted to column footings below my slab on grade. Design of Reinforced Concrete Slabs 107 B = 1.2x 1 where x = distance of load-from support closest to load I = effective span. 5. However, 1.
