［摘要］利用OpenSees有限元軟件建立了具有相同框架部分的雙跨搖擺自復位結構模型和普通框架結構模型，并對其進行靜力彈塑性分析和彈塑性時程分析。通過對比兩種結構的承載能力、變形和結構耗能，得出雙跨搖擺自復位結構具有震后殘余變形小、抗震性能良好和結構可恢復等優(yōu)點。分析結果表明：雙跨搖擺自復位結構能夠保證其在地震作用后僅替換耗能器后繼續(xù)使用，為震后結構的修復節(jié)省了成本，具有很好的工程應用前景。

Abstract:A double rocking self-centering structure and a frame structure with the same frame system were established by using the finite element program OpenSees. Both pushover and elamsto-plastic time-history analyses were carried out. The carrying capacity，deformation and structural energy dissipation were compared to illustrate that the double rocking self-centering system has advantages such as small residual deformation, good seismic performance and structure recovery ability. Analysis results show that double rocking self-centering structure ensure its function continue to use without repair after the earthquake, which save cost of the structure and has good engineering application prospects.
Keywords:double rocking self-centering structure; frame structure; pushover analysis; elasto-plastic time-history analysis
