兰博基尼展厅钢结构分析与设计

Analysis and Design of Steel Structure of Lamborghini Exhibition Hall

郑州兰博基尼展厅钢结构框架柱均倾斜,且局部存在大跨度幕墙桁架,结构计算分析除考虑整体初始缺陷及P-delta效应外,还要对结构进行屈曲分析及几何非线性的极限承载力分析,验证结构整体稳定;通过对结构进行Pushover静力弹塑性分析,分析结构在逐级增加的侧向荷载作用下塑性铰发展及分布,最终证明设计满足结构安全度要求。

The steel frame columns of Zhengzhou Lamborghini Exhibition Hall are inclined,and there are largespan curtain wall trusses in some areas.In addition to considering the overall initial defects and P-delta effect,the structural calculation and analysis should also carry out buckling analysis and geometric nonlinear ultimate bearing capacity analysis to verify the overall stability of the structure.Through the Pushover static elastoplastic analysis of the structure,the development and distribution of the plastic hinge of the structure under the gradually increasing lateral load are analyzed,and fi nally it is proved that the design meets the requirements of structural safety.
