The meaning of cqc ( t ) algorithm is the difference in time domain between the peak value location in time axis of input earthquake and model response of structure, which is called delay time. through the delay time calculating of a series of oscillators with different damp ratio and natural vibration frequency, it is found that it will bring biggish error if the cqc algorithm applied on the structure which has long period, and the time dependent cqc ( t ) algorithm could solve the problem easily
Cqc （ t ）方法的意義在於輸入地震動峰值與結構模態響應峰值在時間軸上的時間差，我們稱之為延遲時間，通過計算具有不同周期和阻尼比結構的延遲時間，發現對于自振周期比較長的結構， cqc方法會帶來比較大的誤差，而基於時程的cqc （ t ）方法能夠解決這個問題。 -
Firstly, the time - dependent spectrum of an earthquake wave estimated by the wavelet analysis is proposed in the paper. it can consider for the earthquake non - stationary frequencies in the study of earthquake ground motions. then, the artificial earthquake waves are computed using the trigonometric series model that includes the instantaneous spectrum
本文應用小波分析理論首先對地震波的瞬時譜進行估計，此時的瞬時譜可以考慮地震動的頻率非平穩性；然後將估計的瞬時譜帶入三角級數模型生成人工地震波。
