【摘要】 提出了具有多个非线性区的结构系统动响应分析的预测－校正方法，并对典型算法的稳定性进行了讨论。该方法将结构划分成若干个子系统，通过对各子系统边界状态的预测使整个系统得以解耦，真正的系统状态则在子系统各自的控制方程中校正。方法不仅避免了子结构法中的静凝聚，提高了求解效率，而且还适用于求解力学性态差异较大的系统间的耦合问题。更多还原

【Abstract】 Predictor-corrector methods for dynamic analysis of structures with local nonlinearity are presented and stability of the methods is discussed. The structure is divided into several subsystems and is uncoupled by predicting boundary states, and then, the real responses of the subsystems are found out from their governing equations. The proposed methods not only avoid the static condensation procedures which are needed in substructuring methods, but also are suitable for coupling systems with different mechanical characteristics.更多还原
