强间断法的重要特征是在连续的位移场中研究位移不连续的问题，通过在间断上引入附加应变来模拟间断。

The essential features of the method are to study displacement discontinuity problems in continuous displacement field and to simulate discontinuity by introducing enhanced assumed strain.

该文还应用静力凝聚法，凝聚掉平面内位移和转角自由度，这样，求解特征值问题的工作量将大大减少。

The static elimination method is used to eliminate the in plane and rotation displacements, thus the time for calculating the eigenvalue problem is decreased greatly.

结论为：无论框架的结构和荷载特征如何，在满足应力约束的前提下，只要恰当改变梁或柱的截面尺寸，用复形法即可得到位于位移约束边界上的最优点。

This model is based on a complex shape model and with it the optimal result can be obtained for most light frame structures and the restraining conditions can be satisfied.
