用转角弯矩矩阵确定压杆的临界荷载

The Calculatiou of critical load by torsion angle-bending moment matix

本文采用统一的转角弯矩矩阵来计算压杆的临界荷载 ,其解与传统方法的解完全相同 ,可适用于各种边界条件 。

This article adopted the unified torsion angle-beuding moment matrix to calculate the critical load of the push-brace.The solution is the same with the traditional one completely.It is a simple and convenient means to ascertain the critical load of the push-brace,and applicable to diversified border condition.
