| 摘 要： | 为克服普通薄壁C型钢构件在宽厚比较大时滞回性能差的缺点，首先对具有相同宽厚比的C型钢和加劲C型钢压弯构件的滞回性能进行了比较，结果表明加劲可有效改善此类构件的滞回性能；然后对具有中间加劲的C型钢构件在压弯循环荷载下的滞回性能、变形情况以及破坏模式进行了深入分析；研究了加劲设置对构件性能的影响，得出了合理的加劲布置方式；最后采用延性系数对中间加劲薄壁C型钢构件的抗震性能进行了评价，给出了设计建议。

| Abstract: | The hysteretic behavior of common C steel members with large width-to-thickness ratio is bad.In order to overcome the weakness,the hysteretic behavior of C steel members with and without intermediate stiffener were compared at first.The results show that the intermediate stiffener is effective to modify the hysteretic behavior of thin-wall C steel members.Then the hysteretic behavior,deformed shapes and the final failure modes of C steel members with intermediate stiffeners under constant compression and cy... |
