Structural design of gymnasium of Beihang University Qingdao campus
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.
