摘　　要：绍兴体育会展馆屋盖结构为梁端刚接张弦桁架,与梁端简支的普通张弦梁在受力特点上有较为明显的区别,故其拉索布置应有所区别。研究表明,不同预应力索端节点位置对张弦桁架内力、整体稳定都有较为明显的影响,对竖向位移影响较小,几乎不影响结构整体动力性能。综合分析后得出了最佳索端节点位置。深入对比三种典型横向支撑系统布置方式的静力、动力及屋盖整体稳定性能发现,间接连续布置的横向联系桁架对屋盖结构整体的综合性能最为有利。Rigid connected truss string is adopted in the roof of Shaoxing Sports Exhibition Hall.Compared with hinged connected truss string,some distinguishing features of bearing capacity have been found.Therefore,the arrangement of pre-stressed cables is different.Several schemes had been researched,which have different position of pre-stressed cable＇s stretching end.The results indicate that the position greatly influences on internal force and overall stability of these truss strings.Also,it has little influence on vertical displacement,and it does not change the dynamic performance of the structure.The best position of pre-stressed cable＇s stretching end is proposed by analyzing of these results.The static behavior,dynamic performance and overall stability capacity of three transverse brace system with typical arrangement modes were studied.The results show that the comprehensive properties of the whole roof structure are the best while indirect continuous transverse truss has been arranged.
