| 摘 要： | 借鉴成都新世纪国际会展中心钢结构部分的空间张弦桁架屋盖结构，设计一种下部是预应力空间桁架和上部梁板结构组合成的新型张弦桁架结构型式，通过大型有限元软件Ansys对该结构进行了静力仿真分析，并研究了分阶段施工对结构受力性能的影响。结果表明，协同工作有效地提高了结构的整体刚度，明显改善了结构的变位和内力。

| Abstract: | According to an engineering project, a new type of BBS is conceived in this paper and its static behavior is analyzed, in addition, the construction stages are taken into account as well by the linear finite element method. It was shown by computed examples that the deformation and the truss stiffness and the overall stability are improved effectively because of the adoption of the concrete slab. |
