Given: A bracket as shown subjected to a nominal dead load of 8 k and a nominal live load of 52 k. Assume the thickness of the angles is ½“, and the supporting member has a thickness greater than that of the angles. Fy = 50 ksi. Note: the bracket plate is welded to the angles. Find: a) The number of 7/8" A325X bolts required if prying is neglected b) What angle thickness is required to essentially eliminate prying effects?
