摘要
在文献 [3]的理论研究基础上 ,提出了连续斜梁桥在偏心活荷载作用下的内力近似计算图式和内力增大系数的近似计算方法。通过算例的分析结果表明 ,本法的精度能够满足设计要求 。
On the basis of theoretical study of reference document , the approximate calculation graphic expressions of internal force and an approximate calculation method of internal force increasing coefficient of continuous skew girder bridges are put forward under eccentric live loads. The results of analyzing calculating examples show that the precision of this method is up to design requirements and cut down the calculation time of designers.
