［摘要］   通過不同的計(jì)算方法，不同的地震激勵(lì)方向，單維與多維地震響應(yīng)等內(nèi)容的研究，探討了常州體育館橢圓形索承單層網(wǎng)殼結(jié)構(gòu)在地震作用下的內(nèi)力及位移響應(yīng)的特點(diǎn)，特別對(duì)比了屋蓋單體模型與屋蓋同下部混凝土框架結(jié)構(gòu)組成的整體模型的地震響應(yīng)。分析結(jié)果表明，橢圓形索承單層網(wǎng)殼短軸桿件的地震響應(yīng)大于長軸桿件的，多數(shù)桿件在多維地震下的反應(yīng)大于單維地震下的，應(yīng)采用整體分析模型計(jì)算屋蓋結(jié)構(gòu)的地震響應(yīng)。

Abstract:Through comparison of different calculation methods, different directions of earthquake excitation, one-dimensional and three-dimensional seismic analysis and other studies, the seismic responses of the elliptical cable-supported dome used in Changzhou Gymnasium were investigated. The seismic responses of the separated roof model and the integral model of the whole building were also compared. The results show that members at minor axis bear higher seismic response than those at major axis, three dimensional seismic response is higher than one-dimensionals, and analysis using integral model of the whole building is preferred than the separated roof model.
Keywords:Changzhou Gymnasium; cable-supported dome; response spectrum; time-history analysis; virtual excitation; three-dimensional seismic analysis; integral model
