A 370mm x 450mm base plate is used to transmit is load from a W31x79 steel column to a 520mm x 600mm concrete pedestal. Properties of W31x79 d = 306mm bf = 254mm A = 10100mm2 For steel: Fy 248MPa For concrete: fc' = 21Mpa It is suggested that the maximum moment for the base plate be computed at distances approximately 0.80bf and 0.95d. The allowable bending for the base plate is taken as 0.75Fy. a) Find the allowable bearing pressure on the concrete. b) What is the allowable axial load for the column without exceeding the allowable bearing stress of the concrete pedestal? c) What is the required thickness of the base plate?

Question
A 370mm x 450mm base plate is used to transmit is load from a W31x79 steel column to a 520mm x 600mm concrete pedestal.
Properties of W31x79
d = 306mm
bf = 254mm
A = 10100mm2
For steel: Fy 248MPa
For concrete: fc' = 21Mpa
It is suggested that the maximum moment for the base plate be computed at distances approximately 0.80bf and 0.95d. The allowable bending for the base plate is taken as 0.75Fy.
