| 摘 要： | 本文介绍了一种用于冷弯薄壁型钢结构的新型组合墙体,并研究了该墙体结构的抗震性能。通过弹塑性时程分析,比较了采用不同组合墙体的3种冷弯薄壁型钢结构在8度和9度罕遇地震下的位移和内力反应。初步分析结果表明,由于新型组合墙体具有较好的抗剪性能,采用该墙体的冷弯薄壁型钢结构可以在抗震设防烈度较高的地区使用。

| Abstract: | A new type of composite wall used in cold-formed thin-wall steel structure was introduced in this paper, and also the seismic performanee of this wall was studied. By using the elastic-plastie time-history analysis method, the displacement and internal force response of three different structures was cornpared under the rare earth- quake of eight and nine seismic fortification intensity. The result shows that this new kind of waU has good shear properties and can be used in cold-formed thin-waU steel structure built in the areas with high seismic fortification intensity. |
