摘要
采用能量原理在广义刚性横梁法的基本假定下 ,横梁为不变形的刚性梁 ,根据单根斜梁在单位力 (或单位矩 )作用下的一般计算公式 ,导出了斜梁桥荷载横向分布的计算公式 ,推出了斜梁桥通用的荷载横向分布的计算公式。并对正梁桥、平行四边形斜梁桥等几种特例下各系数进行了计算。
In the paper, the calculating formula of transverse load distribution for the skew girder bridge is deduced by using energy method based on the general formula of single skew girder by the action of force per unit (or torque per unit) under the basic hypothesis of generalized rigid transverse girder—the transverse girder without deformation. Moreover,the general calculation formula of transverse load distribution is deduced for the skew girder bridge.Several factors under some special conditions for the straight girder bridge and the skew girder bridge with parallelogram are calculated .The method is specially suitable to the calculation of transverse load distribution for the narrow girder bridge simplified as grids.
