Abstract
The two methods of seismic response energy computation respectively based on time domain immediate integration and wavelet transform were studied. And the energy computation based on wavelet transform was deduced. Through practical case,the response energies of same structure under different seismic waves were computed respectively by the two methods. The results show that each of the two energy computation methods has its respective advantages. The energy computation method of time domain immediate integration can reveal the nature of the relationship between the seismic responses of the structure of energy absorption and dissipation. The energy computation method of wavelet transform may practically reveal the distribution of seismic energy by spectrum,and define the energy change in the diffusion of seismic wave in structure.
