摘要:
对框架与剪力墙基础隔震结构的高宽比限值与上部结构动力响应规律进行仿真分析，采用PKPM进行框架和剪力墙结构的结构设计，并通过ETABS软件对两种结构进行隔震分析。为了更好地表征结构隔震效果，引入层剪力比、层弯矩比、层位移角比和周期比的概念，对不同高宽比结构隔震前后的动力响应进行对比。分析结果表明:高宽比为4的框架结构隔震后支座拉应力超限，而剪力墙结构的支座尚未出现拉应力。现有抗规规定的高宽比限值仅适用于框架结构，而剪力墙结构的高宽比限值不宜大于7。此外，研究结果还表明框架隔震结构的隔震支座更易出现拉应力超限，而剪力墙结构隔震支座的压应力更容易超过限值。
Abstract:
The paper analyzes the limit value of the aspect ratio of the frame and shear wall base isolation structure and the dynamic response law of the superstructure，designs the frame and shear wall structure by using PKPM，and analyzes the seismic isolation of the two structures by using ETABS software. In order to better characterize the seismic isolation effect of the structure，the concepts of story shear ratio，story bending moment ratio，story displacement angle ratio and period ratio are introduced to compare the dynamic responses of structures with different aspect ratios before and after seismic isolation. The analysis results show that the tensile stress of the support of the frame structure with an aspect ratio of 4 exceeds the limit after seismic isolation，while the support of the shear wall structure has not yet appeared tensile stress. Research results show that tensile stress of base-isolated frame structure with aspect of 4 is over limit，while there is no tensile stress for the corresponding isolated shear wall structure. The limit of aspect ratio in Chinese seismic code for buildings is only suited for the isolated frame structure，and the suggested aspect ratio for isolated shear wall structure is not greater than 7. Moreover，the research results also show that the tensile stress of isolators in isolated frame structure is more prone to be out of limit， whereas the compressive stress of isolators in isolated shear wall structure is more likely beyond the limit.
