Energy consumption analysis of energy dissipation structure with fail-safe layers

阐述了破损安全与消能减震的基本原理与发展现状,基于结构抗震的能量分析方法,分析带破损安全层消能减震结构耗能情况.采用破损安全与消能减震理论相结合的方法来大量耗散地震能量,提高结构抗震能力.利用SAP2000软件,分别建立模型进行抗震性能分析.结果表明:从抗震性能与经济性综合考虑,双柱框架消能减震结构性能优越,可以有效降低楼层的层间位移和成本;其单个阻尼器耗散的地震能量较大,能够降低主体结构构件的耗能,保证结构的承载能力;可以避免底层设置双柱带来的安全隐患.

The basic principles and the current status of development of fail-safe design and energy dissipation were introduced,and the energy consumption of energy dissipation structures with fail-safe layers was analyzed based on the seismic energy analysis of structures.The fail-safe design and energy dissipation theories were used to effectively dissipate seismic energy and improve the seismic resistance of structures.The models were established by SAP2000 software to analyze the seismic resistance of structures.The results show that in terms of seismic resistance and cost effectiveness,the energy dissipation frame structures with double columns have superior performance,and the double-column design can effectively reduce inter-story displacement and cost.A single damper can absorb a large amount of seismic energy and reduce the energy consumption of primary structural members to ensure the bearing capacity of structures and avoid the safety hazards due to the double-column arrangement on floor.
