| 摘 要： | 以某展览馆屋盖工程为例建立有限元模型,利用ANSYS有限元软件及其APDL参数化语言建模计算分析,并在张弦管桁结构各个部位选择部分节点的位移和杆件的轴力,分析非线性对大跨度张弦管桁结构荷载效应的影响。研究表明:90m跨单榀张弦空间管桁结构在静态荷载(主要是指恒载、活载)的作用下,是否考虑非线性,对节点位移和轴力的影响总体较小,对轴力影响相对较大的是撑杆。就整体结构而言,材料非线性的影响较小。 |

| Abstract: | An exhibition hall＇s roof project was regarded as the engineering background, the ANSYS finite element software and APDL parametric design language were used, some node displacements and the axial forces were selected in order to analyze load effects for non-linear of long-span spatial tubular truss string structure. The results showed that the effects of nodal displacements and the axial forces were small whether to consider non-linear, the impact of pole＇s axial forces was relatively large under the static load （mainly refered to the dead load, live load）. On the whole structure, the effects of material nonlinearity was very small. |
