宽肢薄腹H形截面钢柱的滞回性能

Research on the hysteretic behaviour of H-shaped steel columns with big width-to-thickness ratio plates

根据宽肢薄腹构件的特点,完善了多弹簧非线性数值分析模型;通过试验对比验证了模型的适用性;根据试验和数值计算结果,对这类构件的滞回性能进行了分析;提出在抗震设防区的多层钢框架结构中应用宽肢薄腹构件的可行性。

The multispring model is improved based on the characteristics of steel members with big widthtothickness ratios and is proved by tests. A series of numerical simulation and their results for the kind of steel members are analysized. It is proposed to apply this kind of members in steel frames under certain conditions in areas of earthquake protection.
