| 中文摘要: |
| 以某工程为例，运用大型有限元分析软件MIDAS/GEN对框架-核心筒结构进行分析。并通过对层间位移角曲线、层间位移曲线、塑性铰分布状态等方面的模拟计算与分析对结构的抗震性能进行的评估，结果表明该结构在地震力作用下能够满足使用功能要求并分析出楼层薄弱环节，为楼层加固提供依据。 |
| 英文摘要: |
| Taking an engineering as an example, this paper applies the finite element analysis software MIDAS/GEN to make a static elastic-plastic analysis on frame-core tube structure.By Simulation and analysis of inter-story drift ratio, inter-story displacement and the distribution of plastic hinge distribution state , this paper aims to evaluate the structural seismic behavior. The results shows that under seismic action this structure can satisfy application requirement and can determine the weak links in the structureand thus offers foundation for consolidation of the floor. |
