苏州文博中心项目包含吴江博览中心(南区)和苏州大剧院(北区)两大建筑,两建筑造型新颖独特,建筑使用功能要求繁多,且建筑空间关系相对复杂。高、低位两条飘带更是本项目亮点,其体型复杂,为扭曲的空间桁架结构,通过变换角度最终与南北区两栋建筑连为一体。对飘带进行了风荷载、温度作用、地震作用分析,提出了飘带结构整体稳定及上人舒适度问题的解决方案,并简要介绍了飘带下部两大建筑的结构体系、超长悬挑的解决方案和一个新型桁架端部节点。
There are two major buildings, namely, Wujiang Expo Center (South District) and Suzhou Grand Theater (North District). The two buildings are unique and unique in style. They require a great variety of functions for building use, and the relationship between the buildings is relatively complicated. High and low two streamers is the highlight of the project, its complex, as a distorted space truss structure, through the transformation point of view and eventually North and South two buildings as a whole. The paper analyzes the effect of wind load, temperature and earthquake on the streamers, puts forward the solution of the overall stability of the streamer structure and the man comfort, and briefly introduces the structural system of the two major structures in the streamer, the solution of the overlength cantilever And a new truss end node.
