摘要:
通过三维有限元模型对Π形梁斜拉桥主梁剪力滞特性进行了参数分析,主要考虑了预应力、桥面横坡以及小纵梁的影响,并将有限元模型结果与实桥检测数据进行了对比,验证了其可靠性。结果表明:预应力对Π形截面斜拉桥主梁轴向应力的横向分布规律有明显影响,计算中不可忽略预应力束的影响; 桥面横坡也是影响Π形截面主梁斜拉桥剪力滞效应的一个重要因素,尤其是对顶板中央处的纵向正应力影响较大; 在桥面板沿纵向增设小纵梁是减小剪力滞效应的一种有效方法,对于高度较小的纵梁可以显著改善应力分布。
Abstract:
To study the shear lag effect in cable-stayed bridge with П-shaped cross section, a parametric analysis using finite element analysis was carried out, in which the parameters, such as prestress, transverse slope of bridge deck and little longitudinal beams were considered. The credibility of the finite element model was validated by comparison of its results with the test results of the bridge. The results indicate that the prestress has much effect on the shear lag, and it should not be neglected during calculation. Transverse slope is another important factor to influence the shear lag effect, especially influence the longitudinal normal stress near the middle area of the deck. It also shows that adding longitudinal girders can improve the stress distribution obviously.
