摘　　要：研究了一个静不定杆系的内力求解问题。由于静不定杆系内力的矩阵与位移的矩阵是互为转置矩阵,所以可方便求得静不定杆系的变形协调条件。针对该静不定杆系的内力求解问题,指出有关文献给出的该静不定杆系的变形协调条件是错误的。The equation solving problem of internal force of a statically indeterminate rod system is studied.Because the matrix of internal force and the matrix of displacement of statically indeterminate bar system are transposed each other,the deformation compatibility condition of statically indeterminate bar system can be easily obtained.Aiming at solving the internal force of statically indeterminate bar system,it is pointed out that the deformation compatibility condition of statically indeterminate bar system given in relevant literatures is wrong.
