【摘要】 结合实例,利用ANSYS有限元软件,采用三维空间有限元模型,对钢筋混凝土框架结构、门式刚架及加层后的整体结构进行了模态分析和谱分析,获得了结构的动力特性和地震作用效应的变化规律,为轻钢加层厂房的应用提供了一定参考。更多还原

【Abstract】 Based on the actual case,the structural dynamic characteristics and seismic responses of the frame structure,the rigid portal frame and the overall construction were offered by the modality and the spectrum analysis with the use of the ANSYS finite element software on the three-dimensional space finite element model.It provides a background information and reference to the structural engineers for their design.更多还原
