賈劍輝1，辛?xí)赠i2，楊樹標(biāo)1（1 河北工程大學(xué)土木工程學(xué)院，邯鄲 056038；2 煤炭工業(yè)鄭州設(shè)計(jì)研究院有限公司，鄭州 450007）[摘要] 進(jìn)行了復(fù)合隔震模型振動臺試驗(yàn)，通過調(diào)整隔震層中彈性滑板支座數(shù)量，研究隔震層摩擦承壓比的變化對結(jié)構(gòu)基底剪力系數(shù)、位移反應(yīng)及頻譜特性的影響。試驗(yàn)結(jié)果表明，彈性滑板數(shù)量適中的復(fù)合隔震結(jié)構(gòu)，在合理摩擦承壓比范圍內(nèi)時，是一種隔震性能良好的隔震體系。[關(guān)鍵詞] 復(fù)合隔震; 彈性滑板; 振動臺試驗(yàn)中圖分類號：315-8文獻(xiàn)標(biāo)識碼：A文章編號：1002-848X(2012)10-0124-03Study on shaking table test model in composite isolation with elastic sliding bearingsJia Jianhui1, Xin Xiaopeng2, Yang Shubiao1(1 College of Civil Engineering, Hebei University of Engineering, Handan 056038, China; 2 Zhengzhou Design and Research Institute of Coal Industry, Zhengzhou 450007, China)Abstract: Shaking table tests on a model of composite isolation structure were performed. By adjusting the number of the elastic sliding bearings in the isolation layer, the influences of the change of friction bearing ratio on the shear coefficient of the model, displacement response and frequency spectrum characteristics were studied. The experimental results show that the composite isolation system has good performance when the number of elastic sliding bearings is moderate and the friction bearing ratio is reasonable.Keywords: composite isolation；elastic sliding bearing；shaking table test作者簡介：賈劍輝，副教授，Email：yangsb59@163.com。參考文獻(xiàn)［1］楊樹標(biāo), 李振寧. 幾種隔震體系的地震反應(yīng)分析［J］. 特種結(jié)構(gòu), 2001, 18(1): 36-38.［2］楊樹標(biāo), 周書敬. 砌體復(fù)合隔震結(jié)構(gòu)設(shè)計(jì)方案的合理選擇［J］. 建筑結(jié)構(gòu), 2001, 31(3): 64-66.［3］楊樹標(biāo), 馬裕超，李旭光，等. 復(fù)合隔震結(jié)構(gòu)模型振動臺試驗(yàn)研究［J］.地震工程與工程振動, 2010, 30(1): 142-146.
