摘要
以文献[2]中的刚性横梁法理论公式为依据,并在离散图中引入了附加水平刚臂,从而建立了改善的斜梁桥荷载横向分布系数的计算模型。按本文模型对一座桥例进行了计算,其结果与按文献[2]的理论分析值完全吻合。此外,模型还可以推广应用到需要计入中横梁弹性变形影响的荷载横向分布分析的问题上。因此,它对设计人员来说,是十分具有实用意义的。
Based the theoritical formulae of rigid diaphragm beam method in reference（2） and introduced the additional horizontal rigid arms into the separative scheme, the improving calculating model of load transverse distrubution factors for skew beam bridges is established. The results of an example calculated by this model completty is coincided with those by theoritical formulae（2）. In addition, the calculating model of this paper my be applied extensively to analys the same problem that must take the elastic deformation effect of middle dirphragm beam into account. Therefore, It has the fully practical significance for designers.
