V形墩斜交刚构桥受力性能分析
Mechanical Behavior Analysis of Skew Rigid Frame Bridge with V-shaped Piers
摘要
Abstract
The V-shaped pier continuous rigid frame bridge tends to be more complex on mechanical behavior when being constructed as a skew bridge in order to adapt to the terrain.Especially the bending-twisting coupling effect,negative bearing reaction,overall movement and cracking of the box girder,which results from the skew angle,cause serious harm todaily operations of the bridge.By using the grillage method,a finite element model of a three-span V-shaped pier skew rigid frame bridge is established first to compare and analyze the effects of actions,including the internal forces,bearing reaction and displacement.Then relevant spatial mechanical properties are found,which has theoretical significance and practical value for the design and construction of skew rigid frame bridges with V-shaped piers.关键词
