Problem 4 A steel column carries a factored building load of 75k to a base plate bolted to a concrete footing pad. The column used is W8 ×40 and measures 36ft long. a) Determine the average compressive stress developed in the W8x40 column. b) Determine the bearing stress between the baseplate and the concrete footing. Calculate the weight of the beam and add it to the 75k factored load.
