【摘要】 通过有限元分析软件SAP2000计算分析,研究了在阪神波、EL-CENTRO波和汶川地震波三种不同地震作用下多层框架基础隔震结构和非隔震结构单向偏心下的地震扭转反应。对比研究表明,对于单向偏心的结构来说,采用基础隔震可明显地减少上部结构的扭转反应,并有效地起到隔震作用。更多还原

【Abstract】 On the basis of calculation and analysis with finite element analysis software SAP2000,response of multistory frame base isolated structure and non-isolated structure to one-way eccentric torsion under the Hanshin wave,EL CENTRO wave and the earthquake wave in Wenchuan was studied.Comparative studies indicate that for unidirectional eccentric structure,base isolation can significantly reduce response of the upper structure to torsion,and effectively play the isolation effect.更多还原
