摘要
通过建立大跨宽箱连续刚构主跨跨中区段空间模型,采用大型通用有限元程序ANSYS计算分析,比较研究了箱底板横肋对其横桥向拉应力的影响,以实现连续刚构主跨跨中下挠的可控制性。
Through establishing the middle span section space pattern of large span continuous rigid frame, the paper calculates and analyzes by the large universal finite elements procedure ANSYS, compares and studies the influence of box bottom cross rib on direction across bridge stress, so as to reach the controllability of down warping in the main span of continuous rigid frame.
