Earthquake engineering is a strong focus of civil engineering research,but the primary problem in this respect is the input of seismic motion.In this paper,the time-frequency localization nature of the wavelet function is used to analyze real ground motion,and a feasible method based on wavelet analysis is proposed.The actual seismic wave of El-Centro and TH2TG055 are adjusted by amplitude adjustment,wavelet transform,and standard response spectra fitting,and are then input into a structural model to analyze the seismic response.During seismic response analysis,this paper also analyzes results of story shear force,inter layer displacement,and story drift angle.Results show an improvement in the transformed seismic waves that meet the needs of earthquake resistant engineering and are useful in engineering applications.
