Civil engineering problem

A bearing plate is to be designed for a W21x62, A36 steel beam
that will sit on a reinforced concrete wall (fc=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 LRFD:
1. Minimum length of bearing plate to prevent web yielding, N
? mm. Round up by 10 mm or 25 mm.
=
2. 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=
up by 10 mm or 25 mm.
? mm. Round
3. Required thickness of the bearing plate if B = 300 mm, N =
200 mm. t =
_?. mm. Round up to the nearest whole
