| 摘 要： | 为使铅芯橡胶支座隔震技术应用于村镇砌体结构,将隔震层设置于地坪以上,本文给出了隔震构造的具体做法。选取典型村镇2层未设构造柱的砖砌体结构房屋为试验原型,按1:2缩尺,设计有隔震层和无隔震层的振动台对比试验。首先采用反应谱分析方法,对隔震和非隔震结构分别选取三条地震波,然后通过数值分析,研究隔震和非隔震结构在输入不同地震波时的地震反应规律,根据数值模拟的分析结果设计结构振动台试验中的传感器布置和加载方案。本文设计的砌体隔震振动台试验方案已试验成功,可为振动台试验设计和研究提供参考。

| Abstract: | In order to apply isolation techniques of lead rubber bearing into the rural masonry structure, and to set the isolation layer in the floor above, we present the concrete practice of isolated structure in this paper. A two-layer typical dwelling house of the rural masonry structure without constructional column was selected as the experimental prototype. The shaking table tests with isolation layer and without isolation layer were designed by 1:2 scale. Three seismic waves were selected for isolated and non-isolated structures by response spectrum analysis method. Then the seismic response rule of isolated and non-isolated structures were studied with different seismic waves input through the numerical analysis. The sensor layout plan and loading schemes in shaking table test were designed according to the results of the numerical simulation analysis. The design scheme of shaking table test has been tested successful. It can provide references for design and research of shaking table test. |
