Abstract: Problems in theory, precision and rationality about design method of anchor bolts of open rigid column base connection subjected to combined axial force and biaxial bending moment which is used now are pointed out. A new direct design method based on assumption of plane section was presented and calculation formula was deduced, which can be used as reference to design.
Keywords: biaxial bending moment; open rigid column base connection; design ofanchor bolts
