橡胶支座应用于底层框架砖房的减震控制研究

Research on the Application of Laminated Rubber Bearings to Seismic Release Control Over Brick Masonry Building Structure with Bottom Course Frames

将橡胶支座应用于底层框架砖房的减震控制中 ,利用非线性时程分析法对多种结构控制体系进行了地震反应分析。结果表明 ,设置橡胶支座的结构控制体系减震效果明显 ,相当于地震烈度降低 1～ 2度 ,可使规范对该类建筑的某些限制放宽。

The laminated rubber bearings are adopted to seismic release control over brick masonry building structures with bottom course frames. The non linear analysis method of response history is used to carry out the seismic response analysis of controlling system of multiple structures. The results indicate that the controlling system of structures with laminated rubber bearings set up has had the apparent effects upon seismic release or reduction,corresponding to reducing earthquake fortification intensity to 1°~2°,whereby rendering the specifications for earthquake to release some limitations on such building structures with laminated rubber bearings.
