| 摘 要： | 通过假设,将结构动力失稳能量判别准则推广到非自治系统中,总结出在非自治系统中,结构动力失稳的能量判别准则,以此可判断出结构在外部激振荷载作用下(如简谐荷载,脉冲荷载,地震波等)的动力稳定性.

| Abstract: | Based on assumption,a discriminant criterion for structural dynamical instability is extended to non-autonomous system.Summarizes the energy judging criteria of structural dynimical instability in non-autonomous system.This criterion could be used to judge dynamical stability of structures under external excitation,such as impact loading,harmonic loading and random loading. |
