利用ANSYS有限元软件，结合具体工程实例，对框架结构直接采用轻钢结构加层建立了三维有限元模型，对原框架结构与加层后整体结构的抗震性能进行了模态分析和时程分析，通过分析比较获得了原框架结构、加层结构和整体结构的动力特性和地震作用效应的变化规律，为相似加层结构的抗震设许提供了一些理论参考．

By using finite elements software ANSYS and in light of the project cases, this paper established the 3-dimensional finite element model of light steel adding storeys directly, and gave good model and time-procedure analyses of earthquake resistance of original frame and integral structures after adding storeys are carried out. Through analysis and comparison, it got the variation trend of dynamic behavior and the varied principles of earthquake response of the original frame structure, adding storeys structure and integral structure, which provides certain theoretical reference for seismic design of similar adding storeys structures.
