[摘要]商丘文化艺术中心主要功能为剧场,除设有入口大厅、观众厅、主舞台外,还在观众厅大跨度楼盖顶上设置球幕影院,球幕影院球形顶(内球)外设有悬挂步道的外球。各功能空间层叠交错,空间关系复杂,如何使竖向荷载、水平荷载传力路径明确、简洁是本项目设计的难点及关键点。采用整体-局部-整体的设计思路,整体构件布置后,先针对各个空间独立设计,再进行整体分析。入口大厅采用单排摇摆柱和交叉圆钢管屋面桁架体系,单层摇摆柱仅承担竖向荷载,水平荷载由周边剪力墙及12m标高混凝土平台承担;观众厅和主舞台在施工阶段释放平面交叉钢桁架体系的水平约束;内球和外球采用单层网壳结构体系,被主舞台、观众厅外侧柱、楼梯间剪力墙、12m标高混凝土平台等切割为不完整球壳。合理布置剪力墙,将各功能空间联系到一起进行整体分析。

Abstract:The main function of Shangqiu Culture and Art Center is theatre. Apart from the entrance hall, auditorium and main stage, a ball-curtain cinema is set up on the roof of the large-span floor of the auditorium. An outer ball with hanging walkway is set outside the ball roof of the ball-curtain cinema. The space of each function region is overlapping and complicated. It was the difficulty and key point of this project design to make the clear and concise transmission paths of vertical load and horizontal load. The whole-part-whole design idea was adopted. After the whole components were laid out, each space was designed independently and then overall analysis was conducted. The entrance hall adopts single row swing column and cross-section steel pipe roof truss system, where single-layer swing column only bears vertical load and horizontal load is borne by surrounding shear wall and concrete platform at 12m elevation; horizontal cross-section steel truss system is adopted in auditorium and main stage to release horizontal constraint in construction stage; inner ball and outer ball adopt the structural system of single-layer reticulated shell structure, which is cut into incomplete spherical shells by main stage, outer column of auditorium, stairwell shear wall, concrete platform at 12m elevation, etc. Shear walls were reasonably arranged to link each functional space to an overall part for analysis.

Keywords:embedded end; performance-based seismic design; horizontal stiffness; plane cross truss; reticulated shell with irregular boundary; concrete hollow truss; shear wall layout
