本文应用变形体虚功原理导出连续梁的影响线方程,用于解决连续梁的内力与位移计算,是把传统的结构力学基本理论和新的计算机辅助设计(CAD)方法相结合的一种探索。
This paper applies the principle of virtual work of deformed body to derive the influence line equation of continuous beam, which is used to solve the calculation of internal force and displacement of continuous beam. It is a combination of the traditional structural mechanics basic theory and the new computer-aided design (CAD) method. .
