摘　　要：建立ANSYS有限元计算模型,对钢支架结构在最不利工况下的静力、特征值屈曲和非线性屈曲特性进行了分析与论证。计算了设计荷载作用下结构的变形、内力、截面应力以及结构的前4阶屈曲模态及相应的特征值屈曲荷载,给出了完善结构和有缺陷结构的非线性荷载位移曲线及极限承载力。结果表明,应用ANSYS软件所建立的模型和采用的计算方法合理,计算结果具有较高的精度,所论证的钢支架结构是一种可靠和稳定的结构承载体系。A finite element model was established by using ANSYS. The static analysis, eigenvalue buckling analysis and nonlinear analysis of the steel frame structure under the most disadvantageous load combinations were carried out. Furthermore, the ultimate bearing capacity and the load-displacement curves of the perfect and/or imperfect frame structure under design loads were demonstrated. The calculation results include the deformations, the internal forces of the structure, the stresses, the first 4-order eigenvalue buckling modes and the buckling loads and the nonlinear analysis solutions. The results also show that the analysis with ANSYS is precise, the model and calculating method is rational, the proofed structure is a reliable and stable structure bearing system.
