摘　　要：根据功能原理建立能量补充方程,并利用静力平衡方程,求解一次拉压超静定问题。该方法同时可用于扭转、弯曲等一次超静定问题的求解。This paper introduces a solution to the first-order hyperstatic structure of bar system which gives the additional equation of energy by work-energy principal, and utilizes the equation of equilibrium to solve the tension-compression redundant problem,which can also solve the first-order hyperstatic problem of torsion and bending.

关 键 词：材料力学 变形能 超静定 拉压
