某连续刚构桥梁单元静力数值分析

Static Numerical Analysis of a Continuous Rigid Frame Bridge

以某连续钢筋混凝土刚构桥工程为背景,采用MIDAS有限元数值计算软件,对该桥的全体梁单元的静力情况进行分析.分析表明,全桥的内力分布规律及应力分布规律均满足于设计规定要求,并且符合刚构桥受力分布一般规律.研究结果为桥梁设计阶段的桥梁空间受力分析提供了数据支撑和设计依据.

In this paper,with a continuous reinforced concrete rigid frame bridge project as the background,MIDAS finite element numerical calculation software is used to analyze the static situation of the whole beam element of the bridge. The analysis shows that the internal force distribution and the stress distribution of the whole bridge are satisfied with the design requirements,and conform to the general law of the stress distribution of rigid frame bridge. The research results provide the data support and design basis for the spatial analysis of the bridge in the design stage of the bridge.
