［摘要］以RC框架結構為研究對象，對其進行基于3種DM的IDA分析。采用SAP2000有限元軟件進行大量的彈塑性時程分析，得到了相關指標的IDA曲線簇以及結構各層和整體的IDA曲線，以此對倒塌判定準則進行評估。結果表明：DM分別為殘余層間位移角θr、最大層間位移角θmax和層間位移角θ的IDA方法中，DM為殘余層間位移角的IDA方法對結構倒塌的判定更偏于保守。

Abstract:The RC framework was taken as the research object, and IDA analysis based on three kinds of DM was carried out. The related indicators of IDA curves, the structural layers and the whole IDA curves were obtained through the research of plenty of elastic-plastic time history analyses by the finite element software SAP2000 and the collapse criterion was evaluated. The results show that among the three IDA methods including taking DM as the residual interlayer displacement angle (θr), the maximum interlayer displacement angle (θmax) and the interlayer displacement angle (θ), the IDA method of taking DM as the residual interlayer displacement angle to judge collapse of the structure is more conservative.
Keywords:RC frame structure; residual interlayer displacement angle; interlayer displacement angle; SAP2000; IDA
