斜交支座的一种新计算方法

在曲线桥梁结构及斜交桥梁结构中,经常会出现斜交支座。在进行结构分析时支座约束即为结构的边界条件,准确模拟支座约束对结构分析结果的可靠性有非常重要的作用。在以前学者研究的基础上,给出了斜交支座的一种新的计算方法,使得编写结构有限元分析软件时更加方便和高效,应用时具有更高计算效率。

A New Computation Method for Skewed Bearings

In the curved bridge and skew bridge structures,it is the often case that the bearings will be arranged in a skewing way.At the time the analysis of the bridge structures is made,the restraints of the bearings are the boundary conditions of the structures,and correct simulation of the restraints of the bearings has a vital importance in the reliability of the analysis results of the structures.In this paper,based on the previous work of other researchers,a new computation method for skewed bearings is provided.With the new method,the compiling of finite element analysis software for the structures will become easier,more efficient and computation efficiency in application will be higher.
