The results of analytical and experimental studies of constructional alloy (A514) steel bolted joints show that A514 steel joints using high strength bolts do not produce desirable behavior in their members if the elements of the joints are designed according to current (1968) practice. The study shows that the ratio of net area to gross member area and the ratio of net area to total bolt shear area need to be considered in the design of A514 steel tension members. Some type of upset end, such as an increase in plate width or thickness in the region of the joint can be used to provide the required net to gross member area to insure yielding of the gross cross section before the ultimate load of the joint is reached.
