摘　　要：利用ANSYS软件建立了干挂石材支撑结构体系数值模型,对结构体系进行竖向静力荷载作用下的受力分析:结构体系在竖向荷载作用下最大侧向位移为0.0288m,最大竖向位移为0.0053m,结构体系中构件的最大屈服应力为110MPa。在7度罕遇地震作用下选取3条不同的地震波EL-Centro波、Taft波和人工波对结构体系进行了动力分析:结构体系的竖向位移基本保持不变,而最大侧向位移出现增大,尤其在Taft波作用下,最大侧向位移达到0.0558m,相比静力荷载作用,其值增加了93.8%。上述研究结果表明,结构体系的竖向和侧向承载力及刚度均满足设计和施工要求。The numerical model of the support steel structure system of dry-suspending stones is established by using ANSYS software,the stress of the system is analyzed under vertical static load,the results show that the maximum lateral displacement is 0.0288 m.and the maximum vertical displacement is 0.0053 m.and the maximum yield stress of the system is 110 MPa.Subsequently,the dynamic analysis of the Structure is carried out.the results show that its vertical displacement remains unchanged,while its lateral displacement is enhanced greatly,the max lateral displacement is at0.0558 m under the action of Taft waves,it increases as high as 93.8%compared with that of static load.From static and dynamic analysis,the stiffness and load-bearing capacity of the structural system can meet the requirements of design and construction.
