[摘要]结合长春奥林匹克公园体育场全张拉索膜悬挑屋盖的建筑特征,通过不同的支座类型和布置方式分别形成斜拉结构体系、完全自平衡结构体系及单向滑动的部分自平衡体系等。建立有限元模型,比较不同体系索的内力和刚度、钢桁架的用钢量、钢结构支座反力以及下部结构的内力分布,以选择最优的结构体系。

Abstract:Combined with the architectural features of the full-stretched cable membrane cantilevered roof of  Changchun Olympic Park Stadium, different types of supports and arrangements were used to form a cable-stayed structural system, a fully self-balancing structural system and a partially self-balancing system for one-way sliding respectively.  Finite element models were established to compare the internal forces and stiffness of different system cables, the steel amount used for  steel trusses, the reaction forces of steel structure supports  and the internal force distributions of the lower structures, then the optimal structural system was selected.

Keywords:Changchun Olympic Park Stadium; cable-stayed structural system; fully self-balancing structural system; partially self-balancing system with one-way sliding
