Abstract

The weak axis of I-section column welded the vertical stiffener to simulate the form of strong axis connection. The seismic behavior of joint region and the affections on the ultimate bearing capacity of beam by changing the thickness of skin panel have been analyzed. The hysteretic behavior of joint region, the flexural bearing capacity of beam, distribution of the stress across the weld at beam flange, ductility and energy dissipation capacity have been discussed. The addition of vertical stiffener can increase the stiffness by 7%-11% and the energy dissipation capacity can be increased by 15%. All of the models' relative ultimate rotation angle of beam-column joint are close to 0.03 rad. The weak axis of I-section column under strong axis affections which ductility factors are greater than 2.The weld edge stress at beam flange was reduced by 4%-6%.
