［摘要］建筑結構在多遇地震下的響應通常通過反應譜分析得到?！督ㄖ拐鹪O計規(guī)范》（GB 50011—2010）中給出的設計反應譜及設計地震分組和場地類別的規(guī)定使結構地震響應分析簡單易行且具有很好的可靠性。選取兩個結構體系不同的高層建筑結構模型，分析其在不同的設計地震分組和場地類別下結構地震響應的差異，評價不同場地特征對高層建筑結構地震響應的影響。結果表明，高層建筑結構的地震響應對場地特征有較大敏感性，且對場地類別的敏感程度比對設計地震分組的敏感程度高。

Abstract: Seismic response under frequent earthquake is usually obtained by response spectrum analysis. With seismic response spectra, design earthquake group and site classification given in Code for seismic design of buildings（GB 50011—2010）, the analysis of structural seismic response is easier and more reliable. Two high-rise buildings with different structural systems were modeled to assess the influence of site characteristic on the structural seismic response. Response spectrum analysis with variation of design earthquake group and site classification was performed on the two building models. The results show that the seismic responses of high-rise buildings have a great sensitivity to the site characteristic, and the sensitivity to the site classification is even greater than that to the design earthquake group.
Keywords: High-rise building; response spectrum; design earthquake group; site classification
