| 摘 要： | 利用能量法分析新型消能摇摆结构体系在地震动过程中的耗能机制,并对其抗震性能进行系统研究。以某已建成的6层框架结构为研究对象,建立新型消能摇摆结构体系的计算模型,利用Opensees软件获得新型消能摇摆结构体系在不同地震动激励下的动力响应,分析其各子结构的耗能部位及所占比例。结果表明:新型消能摇摆结构体系的耗能机制更为合理,其抗震性能优于传统结构体系,为工程设计和研究提供一些参考。

| Abstract: | The focus of this study was the characteristics leading to failure of frame structures in recent major disasters.This study analyzed a new system for energy dissipation using a stiff frame rocking structure.Energy consumption during seismic oscillations was analyzed using the energy method, and a systematic study of the system''s the anti-seismic properties was conducted.With a six-floor frame structure as the research object, a calculation model for the new energy dissipation rocking structure was developed.The dynamic responses of the new system under different seismic oscillations were obtained using the OpenSEES software.Energy consumption and its role in the new were analyzed.Results of the research showed that the mechanism for energy consumption in the new rocking structure was more reasonable, and its anti-seismic properties were an improvement over traditional structural systems. |
