【Abstract】 For welded thin-wall box section, the width to thickness ratio of steel plates is relatively large, local buckling happens easily, and the utilization ratio of materials is quite low for small effective width of steel plates. Both Vertical and longitudinal stiffeners are introduced reasonably within the box sections in this subject, the effect of the stiffeners on the bearing capacity of the members is studied, and the seismic behavior of the welded thin-wall box sections is analyzed by non-linear finite element method.更多还原
