摘要
为研究框架-双肢摇摆墙结构的抗震性能,在有限元软件ABAQUS中建立了纯框架结构、框架-摇摆墙结构和框架-双肢摇摆墙结构3组模型,并对3组模型在不同工况下进行弹塑性动力时程分析。通过分析对比表明,框架-双肢摇摆墙结构的自振周期及地震作用与原框架结构基本相当,在中等烈度地震后修复量减小且损伤集中在连梁易于修复,在高烈度下具有整体的破坏机制和更高的抗倒塌能力。
In this study, three numerical models including framed structure, framed-shear wall structure and rocking coupled shear wall structure were established and analyzed under earthquakes to investigate their seismic performance.The results showed that the period of framed structure is closed to that of the rocking coupled shear wall structure and most damage appears on the connecting beam. The rocking coupled shear wall structure is verified to be a good seismic performance system and deserved to research deeply.
