Abstract：In order to investigate the static behavior of SHS(square hollow section)X-joints under in-plane bending,geometry model and non-linear finite element analysis were carried out using ABAQUS software. Combining with verifying experiment,the failure mode,deformation process and ultimate capacity of SHS X-joints were investigated,the effect of joint action between axial force and bending mement on the ultimate bearing capacity was also discussed.The results showed that,under in-plane bending,tension side of chord protruded,compression side sunk,and the welds in tension side of brace failed.Node chord entered a plas-tic phrase and finally the sample failed due to large plastic deformation.The ultimate capacity increased re-markably as βvalue increasd.Under the joint action between axial force and bending mement,the ultimate bearing capacity decreased.
