摘要
苏州高新区文体中心体育馆屋盖为正交平面桁架结构,鉴于场地条件等原因,该工程采用了累积滑移施工方案。通过施工模拟仿真分析,对该方案的可实施性进行了验证。结果表明:累积滑移施工完成的桁架屋面与设计状态下的竖向变形存在一定的差异,但不是很大,能够满足变形控制的要求,同时,结构杆件的附加应力比与原设计应力比之和不超过设计控制限值,满足相关技术标准的承载力设计控制要求。
The roof of stadium,belonged to the Suzhou high-tech zone＇s culture and sports center,is composed of orthogonal plane trusses. The project adopted the accumulating slipping method because of the site conditions. In this paper,construction simulation analysis was used to check the practicability of the method. The results showed that the roof＇s vertical deformation existed difference between construction and design,but the values were small,which could meet the control requirements of deformation. Meanwhile,the sum of the structural elements＇ additional stress ratio and the original design stress ratio was in the acceptable range of values.
