摘要
Based on the intrinsic characters of the fractal and chaotic dynamic systems of seismic dissipated energy active intensity E d and active intensity of seismic dissipated energy moment I e,the evolutional laws of the long term system and short term system behavior are discussed respectively.Active and passive earthquake control parameters,maintenance decision and inputted energy optimization of system are discussed by means of the predictive results of short term behavior in practical engineering structures; earthquake resistant design probability,maintenance probability,seismic risk analysis and seismic hazard analysis are also discussed by means of the predictive results of long term behavior probability in practical engineering structures.The content might be valuable for the practical applications of earthquake resistance theory and method,and for earthquake control and earthquake reduction problems in practical engineering structures.
