摘要:
为了研究内衬混凝土对变截面波形钢腹板组合箱梁桥剪切与扭转性能的影响,基于模型试验和数值模拟,设计并制作了一个变截面双悬臂组合梁模型,分析了内衬混凝土对变截面波形钢腹板组合箱梁的破坏模态、挠度、剪应力、抗扭刚度的影响,并揭示了不同荷载状态下内衬混凝土与波形钢腹板的承剪比变化规律.试验结果表明:内衬混凝土能显著提高组合梁的抗弯、抗剪及抗扭刚度,明显降低中支点区域波形钢腹板的剪应力,且有限元分析结果与试验结果符合良好;内衬混凝土与钢腹板承剪比随荷载的增加而变化,既有理论计算公式仅适用于弹性阶段.综合考虑结构受力合理性和经济性,实桥设计时两者承剪比可按1∶1进行计算.
Abstract:
In order to study the influence of encased-concrete on the shearing and torsional behavior of a non-prismatic composite girder bridge with corrugated steel webs,a double-cantilever non-prismatic composite girder was designed and made based on the model test and numerical simulation. The effects of encased-concrete on the failure modes, deflection, shear stress and torsional stiffness of a non-prismatic composite girder with corrugated steel webs were analyzed and the variation laws of the shear ratio of encased-concrete and corrugated steel webs under different load conditions were revealed. The results show that the encased-concrete can significantly improve the bending, shearing and torsional stiffness of the composite girder, and significantly reduce the shear stress of the corrugated steel webs in the middle support area. The finite element analysis results are in good agreement with the test results.The shear ratio of the encased-concrete and the corrugated steel webs varies with the increase of the load and the existing theoretical calculation formula is only applicable in the elastic phase.Considering the rationality and economy of the structure, in the design of the actual bridge,the shear ratio of the encased-concrete and the corrugated steel webs can be set to be 1∶1.
