The purpose of this study is to investigate the effect of the aspect ratio of aluminum alloy double layer latticed wall and roof plate structures on the dynamic buckling behavior. In our previous paper, the calculation method of predicting the collapse acceleration induced by the progressive web member buckling has been proposed. And the calculation results of the proposed method have shown a good agreement with the results of the elasto-plastic dynamic buckling analysis.In this study, the elasto-plastic dynamic buckling analyses of the plate structures with the various aspect ratios are carried out using truss elements with the member buckling hysteresis curve model. And an one-degree freedom elastic vibration model is used for predicting the collapse acceleration. As a result, it is seen that the accuracy and adoptability of the proposed method are discussed and the validity is shown in this study.

本研究的目的是研究铝合金双层网格墙和屋顶板结构的纵横比对动态屈曲行为的影响。在我们之前的论文中，提出了预测渐进腹杆屈曲引起的倒塌加速度的计算方法。该方法的计算结果与弹塑性动力屈曲分析结果吻合较好。本文采用桁架对不同长径比的板结构进行弹塑性动力屈曲分析。具有杆件屈曲滞后曲线模型的单元。采用一自由度弹性振动模型来预测倒塌加速度。结果表明，本研究讨论了所提出方法的准确性和适用性，并显示了有效性。
