【摘要】 采用ANSYS软件建立三维模型,对某在建的两层冷弯薄壁型钢住宅静力性能和地震荷载作用下弹塑性性能进行分析,为该类结构体系在高烈度区以及灾后恢复重建中的应用提供依据。分析结果表明:该类结构体系对于高烈度地区具有较好的适应性;该结构体系的纵向刚度较横向小,结构体系第1阶振型以扭转为主,在设计中需引起重视;在地震波作用下,其动力放大系数与同类型的普通钢结构相差不大,但不同的地震波所得到的结果差别比较大,所以在进行时程分析时,要正确选择地震波。更多还原

【Abstract】 Three-dimensional analysis model of a cold-formed thin-walled steel house with two layers which is being built was established by ANSYS.Its elastic-plastic response under the static and seismic loads was analyzed.It could provide some references for the application of this type of structure in high-intensity areas and after-disaster reconstruction.The results show that this type of structure has good adaptability in high intensity areas.The horizontal stiffness is greater than the longitudinal one.It should pay attention to the seismic resistance in the design because the torsion plays a main role in the first mode.Under the seismic load,the dynamic amplification coefficient is the same to the ordinary structure,but the results of different waves have great difference,correct waves should be chosen in time history analysis.更多还原
