山东省某教学楼隔震设计

Seismic isolation design of a teaching building in Shandong Province

山东省某教学楼为混凝土框架结构,采用橡胶隔震支座对该结构进行基础隔震设计。采用PKPM和ETABS软件对该结构进行分析。分析结果表明:ETABS软件可以较好的模拟橡胶隔震支座的性能;通过对结构布置橡胶隔震支座方案,该结构满足降一度设计的要求;隔震支座在重力荷载代表值作用、罕遇地震作用和风荷载作用下的性能均满足规范的要求;相邻隔震结构的隔离缝的缝宽满足规范的要求。

A teaching building in Shandong province is a concrete frame structure,and rubber isolation bearing was adopted for the base isolation design of the structure.The structure is analyzed by PKPM and ETABS software.The analysis results show that ETABS software can better simulate the performance of rubber isolation bearing;through the arrangement of rubber isolation bearing scheme to the structure,the structure meets the requirement of reducing one degree design;the performance of the isolation bearing under the action of the representative value of gravity load,the rare earthquake action and the wind load all meet the requirements of the code;the width of the isolation seams of adjacent isolation structures meets the requirements of the code.
