A bearing plate is to be designed for a W21x62, A36 steel beam that will sit on a reinforced concrete wall (f'c = 21 MPa) 200 mm thick. The bearing plate material has Fy = 345 MPa. The end reactions are a service dead load of 150 kN and live load of 300 kN. Determine the following using ASD: 1. Required minimum width and thickness of the bearing plate calculated assuming it is positioned at the center of the concrete wall . Use length N = 150 mm. B = [B] mm. Round up by 10 mm or 25 mm. Answer: 325 2. Required thickness of the bearing plate if B = 300 mm, N = 200 mm. t = [t] mm. Round up to the nearest whole number. Answers: 35
