目前应用较广的连续梁桥,计算工作比较繁琐。本文应用换算刚度法,根据单跨梁的固端弯矩影响线,求解连续梁的内力影响线,概念清楚,手续简便。
The current application of a wider bridge, the calculation is more complicated. In this paper, we use the method of conversion stiffness to solve the influence line of internal force of continuous beam according to the influence of solid-end bending moment of single span beam. The concept is clear and the procedure is simple.
