摘要
北航青岛校区体育馆主体结构采用框架结构体系,屋盖结构采用两向正交正放网架.本工程存在扭转不规则、楼板不连续、局部穿层柱、个别构件转换等不规则项,属于超限建筑.对工程进行了小震弹性分析和大震动力弹塑性分析,针对结构的薄弱部位采取了一系列有效的加强措施.同时本工程还对屋盖与主体结构的连接方案进行了分析比较,对屋盖桁架的稳定性进行了分析,对屋盖典型的钢结构节点进行了有限元分析,对室内运动场地进行了舒适度分析,对超长结构楼盖进行了温度应力分析.结果表明:结构安全可靠,满足预设的性能目标.
Abstract
The main structure of Qingdao campus gymnasium of Beihang University adopts frame structure system,and the roof structure adopts the two-direction orthogonal grid frame.There are some irregular items in this project,such as torsional irregularity,discontinuous floor,partial penetrating column and individual component conversion,which belong to the over-limit building.Small earthquake elastic analysis and large earthquake dynamic elastic-plastic analysis were carried out,and a series of effective strengthening measures were taken for the weak parts of the structure.At the same time,the connection scheme between the roof and the main structure was analyzed and compared,the stability of the roof truss was analyzed,the finite element analysis of the typical steel structure joints of the roof was carried out,the comfort analysis of the indoor sports site was carried out,and the temperature stress analysis of the super long structure floor was carried out.The results show that the structure is safe and reliable to meet preset performance objectives.
