摘要
剪力滞效应是箱形截面梁普遍存在的一种现象,不仅影响箱梁的应力分布还影响其挠度,致使不同桥型在各种荷载作用下其挠度增加。现详细论述剪滞效应对不同桥型挠度的影响,并总结剪力滞对箱梁挠度的影响程度。
The effect of shear lag is a phenomenon commonly existing in the box section, which not only influences the stress distribution of box girder, but also influences its deflection so as to cause the deflection increment of the different bridges in varying loads. The article discusses the influence of shear lag effect on the different bridge deflections, and sums up the influence degree of shear lag on box girder deflection.
