摘要
以一座钢混组合梁斜拉桥为工程背景,建立有限元计算模型,开展了斜拉桥施工过程及运营阶段力学性能分析,并考虑整体温差变化产生的影响,明确了结构最不利状态。结果表明,主梁、主塔及斜拉索等力学指标满足设计要求。
On the background of steel-concrete composite girder cable-stayed bridge,a finite element model was established to analyze the mechanical properties of cable-stayed bridge during construction and operation,the effect of the overall temperature difference was considered and the most unfavorable state of the structure was identified.The results show that the mechanical indexes of main beam,main tower and stay cable meet the design requirements.
