西交利物浦大学体育馆结构设计

Structural Design of Suzhou Xi 'an Jiaotong-liverpool University Gymnasium

西交利物浦大学体育馆为钢筋混凝土框架结构,典型的柱网尺寸为9 m×13 m,羽毛球馆为27 m×39 m的大空间,屋面采用钢桁架结构,为满足建筑设计要求抽掉羽毛球馆底层的一排边柱,造成屋面桁架梁悬挑9 m,并通过吊柱来承受2层的羽毛球馆楼板的荷载。篮球馆为45 m×39 m的大空间,在5.1 m的标高设有空中内跑道,屋面采用网架结构。由于存在结构空旷、跨度大、大悬挑和底层抽柱等特点,造成平面和竖向多项不规则,设计中针对建筑的不规则采用多种抗震技术措施,通过SATWE和PMSAP两种结构计算软件,分别对结构进行整体和分块计算,结果表明,在小震弹性、中震弹性和大震不屈服的作用下,结构的整体指标和承载力满足规范要求,关键构件的设计满足中震弹性的性能化设计目标,确保了结构安全,可供类似的工程设计参考。

Suzhou XJTLU Stadium is a reinforced concrete frame structure with a typical column net size of9x13 meters.The badminton hall is a large space of 27mx39m.The roof adopts steel truss structure.And through the suspension column to bear the load of the badminton hall floor.The basketball hall is a large space of 45mx39m,with an in-air runway at 5.1m elevation.The roof adopts a grid structure.Because of open structure,large span and large cantilever and the underlying extraction column,the planar and vertical multiple irregular,according to the project characteristic,the design of irregular USES the many kinds of seismic technology measures,aimed at building by SATWE and PMSAP two structure calculation software,whole and partition for the structure is calculated respectively,the results show that the elasticity under small earthquakes,The overall index and bearing capacity of the structure meet the requirements of the code,and the design of the key components meet the performance design goal of the medium earthquake elasticity,ensuring the safety of the structure,which can be used as a reference for similar engineering design.
