1. A beam slab system is shown in the figure below. The size of a typical beam is 400 mm (depth) x 300 mm (breadth) and it is assumed to be simply supported. The concrete strength, fcu, is 30 MPa and steel is Grade 460, design the reinforcement for the beam BI if it is required to support the following loadings: Slab thickness = 140 mm Finishes and services = 1.5 kPa Imposed Load = 4.0 kPa You may consider the beam as an L beam and it is simply supported. The concrete cover is 40 mm. Use R10 for the links. Present your result by a sketch (elevation and section). D= 3 m 4 m 140 B1 4 m 7 m 7 m
