［摘要］結(jié)合長春奧林匹克公園體育場全張拉索膜懸挑屋蓋的建筑特征，通過不同的支座類型和布置方式分別形成斜拉結(jié)構(gòu)體系、完全自平衡結(jié)構(gòu)體系及單向滑動的部分自平衡體系等。建立有限元模型，比較不同體系索的內(nèi)力和剛度、鋼桁架的用鋼量、鋼結(jié)構(gòu)支座反力以及下部結(jié)構(gòu)的內(nèi)力分布，以選擇最優(yōu)的結(jié)構(gòu)體系。
［關(guān)鍵詞］長春奧林匹克公園體育場； 斜拉結(jié)構(gòu)體系； 完全自平衡結(jié)構(gòu)體系； 單向滑動的部分自平衡體系

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
