Question

A reinforced concrete cantilevered beam with a span of 5 m extends from the wall, as shown in the figure below. The beam has a rectangular cross-section and supports a uniform dead load (DL) of 15 kN/m (excluding the self-weight) and a uniform live load (LL) of 25 kN/m. The beam width is restricted to 400 mm. Use 10M stirrups and 25M bars for tension steel. The maximum aggregate size is 20 mm. 1ie 5.5. beam is located in the interior of a building. The con crete and steel material properties are given below a) Find the minimum required beam depth, such that the CSA A23.3 requirements are satisfied, without a detailed deflection calculation b) Design the required tension reinforcement for the beam such that it can carry the design loads Use the beam depth determined in part a) Confirm that the design meets the pertinent CSA A23.3 requirements Provide a design summary Given: f 30 MPa 不= 400 MPa o, 0.65 9,-, 0.85 γ,-24 kN/m 3 c)
