| 摘 要： | 以某航站楼工程为背景，对目前常用的咬边连接式铝合金屋面结构系统进行了抗风承载力数值模拟分析。提出了两步分析法，有效地克服了面板与支托接触分析带来的困难和不便。通过对屋面结构系统各构件的抗风性能数值分析，得到了这种屋面连接系统的失效模式，并获得了该屋面结构系统的抗风极限承载能力以及抗风失效时各构件材料强度的利用效率。研究结果可为铝合金屋面设计提供参考和依据。

| Abstract: | The numerical analysis of a conventional aluminum alloy roof system taken from an actual international airport under wind uplift is conducted. A two-step simulation analysis approach is proposed, which effectively overcomes the computational difficulties brought by the contact between panels and supports. Through numerical analysis of roof components, the failure mode of the roof connection and the load bearing capacity of the roof are obtained. And the efficiency of material strength in each component is evaluated as well. It can provide reference for the design and application of aluminum alloy roof structure. |

| Keywords: | aluminum alloy roof structure connection for wind resistance failure mode numerical simulation load-bearing capacity |
