DISCUSSION ON SEVERAL MECHANICAL PROBLEMS OF INTEGRAL TRANSFER STRUCTURE WITH LARGE-SPAN LAMINATED OPEN-WEB TRUSS
-
摘要: 就一种大跨度叠层空腹桁架整体转换结构的杆件受力性质,施加预应力引起的转换结构杆件轴向压缩对结构的影响,参与整体转换的结构层数变化对其内力及变形的影响,转换结构水平与竖向杆件间的刚度关系以及抗震设计基本原则诸项问题进行了分析讨论,探讨了该种转换结构设计中的几个基本概念问题并提出相应设计建议,进而可为相关工程设计提供参考。Abstract: It is analyzed and discussed that the streassed property of members for an integral transfer structure with large-span laminated open-web trusses, the effect of axial compression of the members on the structure due to prestressing force, the effect of changing the layers of the transfer structure on its internal force and deformation, the rigid relation between the vertical and horizontal members, as well as the principles of aseismic design. Several basic conceptual problems in the design of this structure are also explored, and corresponding proposals are given, which may be a reference for the design of relevant projects.
