【摘要】 文章以文献[1]的巨型框架悬挂结构为算例分析其地震响应。基于简化准则将格构式主结构简化为梁、柱模型后,利用SAP2000软件验算简化的准确性。再利用弹塑性静力分析方法将梁、柱模型简化为层模型,并将层模型的结果与SAP2000软件计算梁、柱模型的结果比较,证实层模型和自编程序的有效性。在此基础上利用自编程序讨论巨型框架悬挂结构(带子结构)和巨型框架结构(不带子结构)抗震性能和地震响应,分析得出子结构对主结构起到了较好的消能作用,对体系主结构起到了一定的保护作用,为抗震结构设计提供参考。更多还原

【Abstract】 To set the mega-frame suspension structure in the first reference as model,it has analyzed the earthquake response.Based on the simplified guidelines,the structure is simplified to a beam-column model,the results of two models have been compared by SAP2000 soft.Then the beam-column model has been simplified to the layer model by elastic-plastic static method.The beam-column model has been calculated by the soft,and the layer model has been calculated by the self-compiling program.Then the results of these two models have been compared.It has proved the validity of self-compiling program and the layer model.Based on these,the self-compiling program was used to discuss the earthquake response of the mega-frame suspension structure and the mega-frame structure without substructure.The analysis revealed that the sub-structure played a good role in energy dissipation for main structure which can also protect the main structure.It provides a reference for the design of anti-seismic structure.更多还原
