摘要
采用室内1∶10模型试验方法,系统研究了荷载作用下大曲率连续钢箱梁桥的剪力滞效应,得到了剪力滞系数沿纵、横桥向的变化规律,并根据箱梁截面受压区构造特点提出了考虑钢板初始弯曲的修正系数。利用空间有限元法对模型桥进行了分析,并与试验结果进行了对比。结果表明,试验数据与理论计算结果比较吻合。
According to the experiment indoors with a scaled model of 1/10, this paper studied the shear lag effect of continuous steel bridge with large curvature, and proposed the variety regularity of shear lag coefficient in the longitudinal and transverse direction. Moreover, the paper offered the correction factor considering the plate~ initial bending. Using finite - element method （ FEM ）, the simulation calculation for the model has been carried out, the results was compared with that of the test. The results show that the test data are consistent with the theoretical ones.
