Elasto-plastic Behavior of RHS Column under Bi-axial Bending Moment

摘要

This paper presents elasto-plastic behavior of RHS column under bi-axial bending moment. First,the strength,stiff ness, and deteriorate behavior under monotonic loading without the axial force was obtained by the simple beam style experiment Secondly, shear stress intensity distribution in RHS column considering bi-axial bending moment was expressed based on the proposed equations in previous studies. From these examinations, the fundamental per formance in RHS column affected by bi-axial bending moment and the axial force is clarified.
