贵阳国际会展中心大型不对称筒式悬挂建筑施工应力控制

Construction Stress Control of Large Asymmetric Tube Suspension Building of Guiyang International Conference Center

贵阳国际会议展览中心C2 201大厦为悬挂式建筑,内部受力形式非常复杂。在工程中运用计算机仿真模拟分析技术对施工工序进行模拟,根据迭代理论设置钢结构施工变形预调值,调整施工过程中建筑体的位形,并通过千斤顶施加或卸载对建筑体的作用力调配建筑体的整体位形及内部应力,从而实现了安装过程中结构自由受力状态,并且确保了竣工时建筑体的几何形态、受力状态符合理论设计值。

C2 201 building in Guiyang international conference is a suspension building and its force form is complicated.Authors use computer simulation technology to simulate the construction process.According to iteration theory,they set preset value in the deformation of steel structure construction,adjust the building configuration in the construction process.Besides,by imposing or uninstalling the force with jack,authors adjust the whole configuration and internal stress of building.In this way,it achieves free stress condition in the installation process and ensures the geometry of the body and the stress state to consistent with theoretical design value.
