本文根据桥跨结构考虑扭转的荷载横向分布计算公式编制了主梁为常截面的荷载最大横向分布系数图供设计直接查用。同时根据“等代简支梁”的原理,把常截面简支梁桥的荷载横向分布方法近似地引伸用于各种体系的变截面梁桥。 一、桥跨结构考虑扭转的荷载横 向分布计算 桥跨结构考虑扭转的荷载横向分布计算公式为:
In this paper, according to the calculation formula of transverse load distribution considering the torsion of bridge structure, the maximum transverse distribution coefficient chart of the load of the main beam as a normal section is designed for direct investigation. At the same time, according to the principle of “equivalent generations of simply supported beams”, the transverse load distribution method of simply supported simply supported girder bridges is extended approximately for the varied cross-section girder bridges of various systems. First, the bridge structure to consider the reverse load lateral distribution calculation Bridge cross-sectional structure to consider the reverse load lateral distribution formula is:
