2022世界杯主场馆钢结构卸载过程分析

Analysis of Unloading Processin of Lusail Stadium for 2022 World Cup

根据2022世界杯主场馆卢赛尔(Lusail)体育场主体钢结构的安装方案,灵活选取适合现场情况的卸载方案,并运用有限元软件Midas对结构卸载过程进行模拟,对结构安全,以及卸载过程中压环与V柱等主要结构变形及应力的变化趋势进行分析,并结合卸载过程实测值对理论计算结果进行了综合对比。理论与实测相结合,进一步论证了该主体钢结构卸载方案的可行性。

Based on the installation method statement of main steel structure of Lusail Stadium,the main stadium of Qatar World Cup in 2022,unloading method statement has been selected flexible.The simulation of unloading process has been done with software of Midas.Authors checked the structure safety and the variation tendency of compression ring and V frame columns displacements and stresses.Actual survey data also is used to comprehensive comparing with calculated value.Combined with theory and actual survey results,conclusions can be draw that the unloading method statement of main steel structure is feasible.
