The applied hybrid seismic isolation technique combines laminated rubber bearings with elastic sliding bearings. Measures of the seismic isolation technique were introduced and the numerical model of the temple hall was established. The performance of the seismic isolation structure and the primary structure under the frequent earthquake, design earthquake, rare earthquake were compared through time-history analysis of column bottom shear, overall relative displacement and top acceleration. It is found that the seismic response of the seismic isolation structure decreases significantly and the seismic resistance of the temple hall is improved.Keywords: ancient timber structure; elastic sliding bearing; hybrid seismic isolation; time-history analysis作者簡介：潘忠煒，碩士，Email:1132046@#edu.cn。參考文獻［1］高大峰.中國木結(jié)構(gòu)古建筑的結(jié)構(gòu)及其抗震性能研究［D］.西安:西安建筑科技大學,2007.［2］汪興毅,楊智良.殿堂型木構(gòu)架古建筑的抗震構(gòu)造研究［J］.合肥工業(yè)大學學報：自然科學版,2007,30(10):1349-1352.［3］薛建陽,張鵬程,趙鴻鐵.古建木結(jié)構(gòu)抗震機理的探討［J］. 西安建筑科技大學學報：自然科學版, 2000, 32(1): 8-11.［4］周乾,閆維明,楊小森,等. 汶川地震導致的古建筑震害［J］.文物保護與考古科學,2010, 22(1):37-45.［5］謝啟芳,薛建陽,趙鴻鐵.汶川地震中古建筑的震害調(diào)查與啟示［J］.建筑結(jié)構(gòu)學報,2010,32(S2):18-23.［6］宋耀春,李占國. 4.14玉樹地震古建筑損害調(diào)查及應(yīng)急性保護對策［J］.青海社會科學,2010,7(4):94-98.［7］劉文光.橡膠隔震支座力學性能及隔震結(jié)構(gòu)地震反應(yīng)分析研究［D］.北京:北京工業(yè)大學,2003.［8］徐彤,周云,李良.結(jié)構(gòu)減震控制技術(shù)在抗震加固改造中的應(yīng)用［J］.建筑結(jié)構(gòu),2000,30(10):63-66.［9］薛彥濤.建筑結(jié)構(gòu)隔震技術(shù)現(xiàn)狀與應(yīng)用［J］.建筑結(jié)構(gòu),2011,41(11):82-87.［10］GB 50011—2010 建筑抗震設(shè)計規(guī)范［S］.北京:中國建筑工業(yè)出版社,2010.［11］DGJ 089—2003 建筑抗震設(shè)計規(guī)程［S］. 北京:中國建筑工業(yè)出版社,2003.［12］JUNYA SAKAI, KINYA TAGAKI.
