低成本基础隔震建筑地震响应与隔震措施研究

摘要

In order to reduce the isolation cost in the underdeveloped areas such as villages and towns,two kinds of low-cost isolation schemes for the town masonry building are put forward,namely,the economic engineering plastic plate rubber isolation structure and the reinforced-asphalt seismic isolation structure.The seismic responses under the action of frequent and rare earthquakes are studied by SAP2000,and the comparison of the two types economic isolation devices on the economy and the isolation effect is carried out.The results show that the combined seismic isolation scheme can reduce the seismic acceleration and displacement response.%为了降低村镇等不发达地区的隔震建筑成本,提出两种适合村镇砌体建筑的低成本隔震方案,即分别采用经济型工程塑料板橡胶隔震结构和钢筋-沥青隔震结构,利用有限元分析软件SAP2000研究其在8度多遇和罕遇地震作用下的地震响应规律.综合两种经济型隔震装置的优点,从经济性与隔震效果两方面与组合隔震方案进行对比分析,结果表明,组合隔震方案在降低成本的基础上,可以更好地降低地震加速度反应和限制位移反应.
