摘要
在薄壁杆件弯扭理论的基础上，提出了用弹性支承连续梁法进行铁路曲线上混凝土简支直梁的空间结构分析方法，即将隔板视为弹性支承，梁当作弹性支承上的连续梁，推导出了空间直梁的单元刚度矩阵。此方法不但可以计算出梁的内力，还可计算出隔板的内力。并通过一个计算实例，与现行计算方法进行了比较、分析。
A calculating method of continuous girder on elastic brace and the derivation of three-dimensional straight member stifness matrix which are based on the bending-torsion theory of thin-walled girder are presented to analyze the spatially straight concrete beams.Diaphragm is regarded as elastic braces,and the beam as continuous girder on elastic brace.Not only can the beam's internal force be calculated by this method,but also the diaphragm's.In the end of this paper,a comparison is made between the proposed method and the now in force by a numerical example.
