摇摆填充墙-框架结构抗震设计方法研究

Study on Seismic Design Method of Rocking Infilled Wall-Frame Structure

以现行框架设计方法为基础,对一种新型的摇摆填充墙-框架结构进行抗震设计方法研究。采用静力非线性分析方法,对比了摇摆填充墙-框架结构与普通填充墙-框架结构和纯框架结构的性能差异。依据GB50011-2010《建筑抗震设计规范》对摇摆填充墙-框架结构分2个阶段进行设计,分别为多遇地震烈度下结构的内力变化和罕遇地震烈度下结构的最大层间位移角验算。最后针对墙体的"摇摆"对框架梁的延性要求提高的问题,简述了需要采取的相应构造措施。

Based on the current frame design method, the seismic design method of a new type of rooking infiUed wall frame structure is studied. The static nonlinear analysis method is used to compare the performance differences between the rockinginfilled wall frame structure and the common infllled wall flame structure and the pure frame structure. According to GB 50011-2010 ＂Code for Seismic Design of Buildings＂, the design ofthe swing filled wall frame structure is dividedinto two stages, respectively the internal force changes o fstructure under the frequent earthquake intensity and the verification o fthe maximum srory drift anagle o fthe structure under rare earthquake intensity. Finally, according to the problem that the ductility requirement of the frame beam is raised by the ＂swing＂ of the wall, the corresponding anti-seismic construction measures are briefly described.
