高层剪力墙结构隔震设计关键技术
|
摘要
针对高烈度地区的实际工程案例,建立有限元模型并进行非线性时程分析。阐述了高层剪力墙结构隔震分析与设计细节。对高层剪力墙隔震结构的转换梁提出了性能设计要求。理论结合实际地分析了本结构的隔震效率。研究结果表明,隔震后结构层间剪力和层间位移明显降低,结构性能指标均能满足相应规范要求。上部结构地震响应显著降低,结构抗震性能得到很大提高。
Based on the actual engineering case in high-intensity area,a finite element model was established to conduct nonlinear time history analysis.This paper expounded high-rise shear wall structure seismic isolation analysis and design details;and put forward required design performance of the transfer beams.Combining theory with practice,the structural isolation efficiency was also analyzed.The research results show that with seismic isolation design,the inter-story shear force and inter-story displacement are significantly mitigated.Corresponding requirements of structural performance indicators in codes can be satisfied.Seismic response of the upper structure is markedly reduced;and structural seismic performance is greatly improved.
