QUESTION:


A W10x112 column rest on a base plate and on a 400 mm x 400 mm concrete pedestal. The pedestal and
base plate are of the same dimensions. Yield strength of steel Fy = 248MPa, effective length of column Le=
W/4 m. Concrete strength fc = W MPa. Use ASD. (Hint Le = kL)

a.What is the allowable axial capacity of the column in kN?
b.What is the allowable bearing capacity of the pedestal in kN?
C.What is the minimum required thickness of the base plate rounded off to nearest safe 5 mm?
