钢管混凝土结构的抗震分析研究

Study on seismic performance of concrete-filled steel tubular structure

钢管混凝土构件在外力作用下均提高了混凝土的抗压性和钢管的抗倾覆性,对不同截面的钢管混凝土柱构成的模型进行研究,通过模态分析了解动力特性,再在多遇地震下进行反应谱法分析,研究模型的内力响应和位移响应。通过模型在地震作用下的变化,为钢管混凝土构件应用在建筑设计中提供参考。

When the concrete-filled steel tubular structure is subjected to external forces,it gives full play to the stability against overturning of steel and compressive strength of concrete. The models of concrete-filled steel tubular columns with different sections were analyzed in the modal analysis and vibration decomposition response spectrum method. Research contents are internal force response and displacement response of the model,they provide reference for the application of concrete-filled steel tube components in architectural design.
