利用ANSYS程序的三维实体单元和子模型技术 ,对某立交桥V形支撑局部结构模型进行了应力分析 ,绘出了各部位等应力迹线 ,并揭示了常规内力分析中所不能发现的一些问题 ,本文结果对确定V形支撑局部构造及结构设计有一定的参考价值
Using the three-dimensional solid element and sub-model of ANSYS program, the stress analysis of the V-brace local structure model of an overpass was carried out. The isokinetic stress trace of each part was plotted and some problems that could not be found in conventional internal force analysis were revealed. The results of the V-shaped support to determine the local structure and structural design have some reference value
