摘要
结合斜腿刚构桥工程实例,建立不同跨径布置、不同斜腿倾角、不同斜腿长度的斜腿刚构桥有限元模型,从内力水平指标上对控制截面的受力情况进行了结构分析,从而得出斜腿刚构桥的优化方法。
For the actual slant-leg rigid frame bridge engineering,finite element model of skew slant-legged rigid frame bridge is established with different span arrangement,different slant leg angles and different slant leg length,the paper analyzed the force level of control cross on structure loading condition,thus provides the optimization design method of slant-leg rigid frame bridge.
