摘要
大跨空间结构广泛应用于大型建筑物中,为保证建筑物的安全,需要对大跨结构进行抗震分析。文中采用ANSYS对某大跨空间结构进行了模态分析,得到了结构的前5阶自振频率。对结构进行了地震反应谱分析,得到了结构在地震反应谱作用下的最大挠度。根据计算结果,大跨结构的抗震性能满足工程要求。
Long-span space truss structure is widely used in large building. In order to ensure the safety of the building, seismic analysis of the long-span space structure should be taken. In this paper, the modal of the long-span space structure is analyzed and gotten the first five natural frequency with AN- SYS is gotten. Spectrum analysis of long-span space structure is taken and the maximum deflection of the structure is gotten. According to the calculation result ture meet the engineering requirements. , the seismic behavior of the long-span space struc-
