ANSYS某空间网壳结构的应力和变形分析

摘要：曲面网壳结构是人们受自然界的启迪，能以其合理的形体来抵抗外荷载的作用，在大跨度的情况下比普通网架结构节约钢材，且造型美观，广泛应用于大型的集会场所和建筑。本文以某国际会议展览中心屋盖网壳结构部分为研究对象，采用有限元软件ANSYS进行了静力分析，得到了该会展中心结构模型在均布荷载作用下的静力变形规律，可以为网壳结构的工程设计提供一定参考。 87658

Title Stress and deformation analysis of a Spatial reticulated shell structure

Abstract Curved surface latticed shell structures is the people affected by the nature of the enlightenment, to the rational form to resist external loads, in large span than ordinary grid structure steel saving and beautiful shape, widely used in large venues and building。 The to an international conference and exhibition center roof reticulated shell structure as the object of study by finite element software ANSYS static analysis, has been the Convention and Exhibition Center structure model under uniformly distributed load under the action of static deformation, can provide some reference for the engineering design of reticulated shell structure。

Keywords Reticulated shell structure finite element static analysis
