苏州文体中心体育馆屋盖为正交平面桁架结构,鉴于结构受力、场地条件等原因,该工程采用了累积滑移施工方案。利用MIDAS软件建立了结构的空间有限元模型,主要借助施工模拟仿真分析对上述方案的可实施性进行了验证,结果显示:在滑移施工过程中,通过调节滑靴高度,并合理借助土建结构的布置,可以显著地降低作用在临时支撑架上的作用力,对于支撑架的设计以及薄弱混凝土构件的受力是非常有利的,而在温差较大地区,温度作用对结构的水平变形影响较大,在施工过程中不容忽视。在滑移过程中,由于刚度的原因,结构的最大变形和最大约束反力均出现在滑移中期。
Suzhou Sports Center Gymnasium roof is orthogonal planar truss structure, in view of the structure of force, site conditions and other reasons, the project uses a cumulative slip construction program. The finite element model of the structure was established by using MIDAS software. The feasibility of the above scheme was verified by the simulation analysis of the construction. The results showed that by adjusting the height of the shoe and using the civil structure Can significantly reduce the force acting on the temporary support frame, which is very beneficial to the design of the support frame and the stress of the weak concrete component. In the area with large temperature difference, the temperature effect exerts a greater influence on the horizontal deformation of the structure Large, can not be ignored in the construction process. During the slip process, due to the stiffness, the maximum deformation and the maximum restraining reaction of the structure appear in the mid-slip.
