假想荷载法的力学本质

Mechanical Essence of Fictitious Load Method

提出了与现行假想荷载法相区别的假想荷载法，并揭示了这种算法的力学本质．在证明虚构状态之间存在互偶平衡后，指出了虚构状态“Ⅰ”即为求得假想荷载项的“计算简图”．

The fictitious load method has been put forward. It is different from the existing method. The mechanical essence of the method is revealed. After proving the reciprocal equilibrium among the several fictitious states, it is pointed out that the fictitious state “Ⅰ” is just the “calculating diagram” for the term of fictitious load.
