一、引 言 具有直线形心轴的连续梁上,居翁(Guyon)的理论证实了当钢筋的线形成线性变换时,推力线保持不变(8)(线性变换指的是:使两个端点固定的情况下,连接支点处钢索位置的直线的转动,曲率保持不变)。 这个定理对于连续梁推力线的分析带来了相当大的简化。事实上,从与推力线重合
I. Introduction Guyon’s theory confirms that the thrust line remains constant as the bar’s line forms a linear transformation (8) (linear transformation refers to moving the two endpoints Fixed case, connecting the fulcrum at a straight line where the cable rotation, the curvature remains unchanged). This theorem leads to a considerable simplification of the analysis of the continuous beam thrust line. In fact, coincided with the thrust line
