有机玻璃直线连续箱梁试验研究

Experimental Study on Plexiglass Straight Line Continual Box Girder

对有机玻璃2跨直线连续箱梁进行了弹性阶段试验,对连续箱梁在均布荷载与集中荷载下的应变变化规律以及剪力滞效应进行了初步研究﹒研究结果表明:均布荷载与集中荷载下剪力滞效应较显著,不同的荷载形式产生不同的剪力滞效应﹒

A preliminary study is conducted for two perspex boxes for cross-linear elastic phase of a pilot study of the continuous box girder in the uniformly distributed load and concentrated load changes under the strain and the shear lag effect. The results show that： the uniformly distributed load and concentrated load shear lag effect under more significant, different loads have different forms of shear lag effect.
