Distribution characteristics of shear lag effect in wide single cell box girder PC continuous bridges with low depth and large width-span ratio and width-height ratio were determined,concerning main loadings in the construction stage and completed bridge stage.
为明确宽跨比、宽高比均较大的低高度混凝土单箱单室连续梁桥在施工和成桥阶段主要荷载作用下的剪力滞效应分布特点,通过空间实体模型与平面杆系模型相结合的有限元法对山东济南黄河三桥引桥预应力混凝土单箱单室宽箱梁的空间应力响应进行了研究。
