| Abstract: |
| The sizes of time-delay certainly will be influence on the structural energy and responses of active vibration control of frame structures.In the range of allowable time-delays,in the paper,both the structural energy and responses are taken as the object function,numerical simulation shows that the object function present a curve state when the time-delay is changed.In the hand of the object function transaction,a no dimensional operation is adopted to eliminate the inconsistent quantity between the structural energy and responses.Meanwhile,considering the randomicity of earthquakes,an improved stochastic Newmark scheme is provided.Finally,a numerical example is presented to show the effectiveness of proposed algorithm. |
