摘要
制作了一个三跨混凝土曲线箱梁桥模型,基于合理的试验流程安排,进行多工况下的普通连续曲线箱梁桥和无伸缩缝连续曲线箱梁桥的剪力滞效应试验,得到两种桥型在试验工况下的剪力滞系数。通过有限段法结果与有限元法、试验数值的比较,进一步验证了基于有限段法分析的本文程序计算多跨无伸缩缝曲线箱梁桥的适用性和准确性。
A three-span continuous curved box girder bridge model was made to meet the specific requirements of the research work of this paper.Under a reasonable experiment process,the shear lag effect of both traditional bridges and jointless bridges with continuous curved box girder is obtained under testing operating loads.The applicability and accurateness of the finite segment model in the paper is proved again by comparing with the results derived from finite element method and experiment.
