Large box girder bridge sections of reinforced concrete are being designed with high width-to-thickness ratios which have never been investigated for buckling behavior. This project will investigate the buckling behavior of reinforced concrete plates in bending and/or compression in order to establish maximum limits. Important parameters, such as creep and nonlinearity will be evaluated.

大型钢筋混凝土箱梁桥截面设计具有高宽厚比，但从未对其屈曲行为进行过研究。该项目将研究钢筋混凝土板在弯曲和/或压缩下的屈曲行为，以确定最大极限。重要的参数，如蠕变和非线性将被评估。
