摘要:
为研究斜拉桥纵隔板对钢桥面板构造细节疲劳应力的影响,基于子模型方法分别建立了钢桥面板和顶板与U肋焊缝、横隔板与U肋焊缝以及U肋对接焊缝的有限元模型,分析不同构造细节的应力特征,确定横桥向最不利加载工况。在最不利工况下提取各关注点处应力时程,采用Goodman公式计算等效应力幅,以等效应力幅来衡量各构造细节处的疲劳性能。针对设置纵隔板影响较大的构造细节,分析设置纵隔板横桥向影响范围。研究结果表明:斜拉桥钢箱梁纵隔板构造增大了横隔板与U肋焊缝的等效应力幅,降低了其疲劳性能,而对顶板与U肋焊缝疲劳受力的影响可以忽略不计,对于与纵隔板相邻的两根U肋对接焊缝,设置纵隔板能够有效改善对接焊缝疲劳区域的受力性能。
Abstract:
To study the effect of longitudinal clapboard on the fatigue stress at structure details of steel deck of cable-stayed bridges,the finite element models of the steel deck, the deck-to-rib welds, the diaphragm-to-rib welds and the U-rib butt welds were developed based on the sub-model method. The stress characteristics at different structural details were analyzed to determine the most critical loading position.For the most critical position, the stress time history of each objective point was extracted. Goodman formula was used to calculate the equivalent stress amplitude, which to evaluate the fatigue performance of each structural detail. For the structural details greatly influenced by the longitudinal clapboard, the influence range was discussed. The results showed that the arrangement of longitudinal clapboard improved the equivalent stress amplitude of diaphragm-to-rib welds, which weakened their fatigue performance. However,the arrangement of longitudinal clapboard had less effect on fatigue performance of deck-to-rib welds. For butt welds, the arrangement of longitudinal clapboard only affected the fatigue stress at butt welds of adjacent U-ribs.
