斜拉立体桁架内力、位移特征分析与设计
Features About Internal Forces and Displacements of Cable-stayed Space Truss and Several Problems in Design
【摘要】 借鉴桥梁工程中斜拉桥及我国建筑工程中屋盖结构的工程经验,提出斜拉立体桁架结构是一种有发展前途的大跨度杂交结构,并对该结构体系的几种形式进行了大量的静力线性与几何非线性分析,得到该结构的受力和变形特征,提出设计中应该意的几个问题和有关参数,供初步设计中参考。
【Abstract】 According to the experience of cable-stayed bridges and roof structures in building engineering,it is presented that cable-stayed space truss is a kind of long span hybrid structure with developing prospect.Some features about internal forces and displacements are obtained from a lot of linear and non-linear analyses.Several problems and related parameters in the process of design can serve as reference for the engineer in the preliminary design.
