框架结构变梁异型节点核芯区弹塑性静力分析

摘要

In this paper, housing construction structural analysis and design software MIDAS GEN were used, through software emulation and contrast becomes shaped beam joint core zone is cut overall cycle structure, displacement, performance points, interlayer shear, story drift angles deformation, as a basis for proposed based on the theory of change under the plastic hinge frame beam abnormal joints, when the strong earth-quake at the beam-column node field value changes just to assess the overall performance of the architecture. The results showed that, shear beam shaped node becomes the core area of the frame structure, and the results will directly affect the internal force and deformation of the structure, while the overall seismic performance of the structure have a greater impact.%运用房屋建筑结构分析与设计软件MIDAS GEN,模拟并对比了变梁异型节点核芯区是否剪切变形下结构整体的周期、位移、性能点、层间剪力、层间位移角等,以此为依据提出了基于塑性铰理论下变梁异型节点的框架结构,在罕遇地震时梁柱节点处刚域值改变时结构的整体性能评估体系,研究表明：考虑框架结构的变梁异型节点核芯区的剪切变形,其结果将直接影响结构的内力与变形,同时对结构的整体抗震性能也产生较大的影响。
