The results show that changes of load angle has a great impact on behavior of Zshaped C columns. The horizontal carrying capacity and the ductility factor reach the minimum as = 60, and at the same time the horizontal displacement reaches the maximum. Proposal: besides working on the two principal axes, the carrying capacity, stiffness and limited displacement about = 60 should be calculated in the practical design.
