Practice Problem 5 The bracket connection shown carries an eccentric load P at an eccentricity e 400 mm. The column and bracket are A36 steel. Diameter of bolt is 22mm in standard holes. Assume that the column flanges an bracket are thick enough that single shear in bolts will control. Shear capacity of one bolt is 45 KN. a) Determine the polar moment of inertia. b) Determine the maximum load P that can be supported by the bracket shown. c) Determine the torsional load on the critical bolt. e=400 mm
