苏州大学体育馆钢结构屋盖施工过程仿真分析

Simulation Analysis of the Construction Process of the Steel Structure Roof of Suzhou University Gymnasium

苏州大学体育馆钢结构屋盖采用空间网架结构,网架采用正放四角锥的网架结构,支撑形式为下弦多支点形式,通过抗震球形支座支撑于周边框架柱。文章采用SAP2000有限元分析软件对钢屋盖进行施工过程仿真分析,结合北斗GNSS技术对施工过程进行监测分析,包含顶升过程以及拆撑卸荷过程,结果表明,理论计算与实测挠度值符合较好,为钢结构屋盖施工过程提供了科学根据。

The space grid structure which used the square pyramid grid structure form was adopted as the roof of Suzhou University Gymnasium.The support which supported by frame columns through seismic spherical bearings was the lower chord multi-support point form.SAP2000 was used to analyze the construction process of steel roof.The analysis included the lifting process and the unloading process.The analysis results show that the measured deflection values are in good agreement with the theoretical calculation values.These provided a scientific basis for the construction process of steel structure roofs.
