摘要
以长沙市洪山大桥塔梁墩固结节段模型试验为基础 ,通过对模型的简化 ,给出了在轴力作用下剪力滞效应的解析解 ,并用模型试验进行验证 ;最后应用空间有限元方法分析大悬臂钢脊骨梁在轴力和弯矩作用下剪力滞效应 。
Based on the experiment in the model of Hongshan Bridge in Changsha city,first,the general solution of the shear lag effect on the axis force is given by predigesting the model. Then the theory is proved correctly with the result of the model experiment. Finally, the tentative analysis of the shear lag effect of cantilever box beam on the horizontal force and bend moment by using the method of finite element is tried to offer, which can be used as reference in designation.
