A W14X145 Column A992 steel carries axial loads of DL=400 Kips and LL=275 kips. Assume a concrete pedestal is 25" by 25" and will be under the base plate. The steel base plate is A36 and the concrete has f'c = 3 ksi. Use the AISC LRFD method only to design a base plate. Note: A36 Fy=36 ksi W14x145 d = 8 in Bf =5 in a. Determine the Required (Demand) Load in LRFD (use appropritate load combinations)
