摘要
利用虚位移原理求解静定条件下构件截面的内力方程,即弯矩方程和剪力方程。该方法直观有效,可以不必求解约束反力,避免由于约束反力计算不准确带来的二次错误,减小了计算工作量;同时该方法丰富了虚位移原理的应用,为静定结构的内力方程求解提供了另一种思路。
Using the principle of virtual displacement, the internal force equation of the member section under the static condition is solved, that is, the moment equation and the shear force equation. This method is intuitionistic and effective. It can avoid the secondary error caused by inaccurate calculation of constraint reaction and reduce the calculation workload. This method enriches the application of virtual displacement principle and provides another method for solving the internal force equation of statically determinate structure.
