摘　　要：根据非线性有限元理论研究了索穹顶结构的受力情况,用有限元分析软件AN SY S建立了某农用仓库的索穹顶结构模型,探讨了其在不同预应力水平作用下的受力情况,分析了索和杆在不同荷载下的内力变化情况及对结构稳定性的影响。结果表明该模型受力合理,可以应用于工程实践。In the paper,the mechanical properties of cable dome was studied according to nonlinear finite element theory,a model of geoponic depository which attributes to cable dome structure was constituted by using the ANSYS software,the mechanical conditions of the structure under different prestress was discussed ,and the inner force variation conditions under different force and its influence on the stability of the structure were analyzed. The results prove that the mechanics properties of the model is reasonable and it can be used in project.
