Title: Analysis method for seismic response in frequency domain based on bearing acceleration input
Abstract: In order to truly reflect the input mode of seismic load and the dynamic response of structures under the seismic action,an analysis method for seismic response in frequency domain based on bearing acceleration input was established,and the dynamic response of structures under bearing acceleration input was studied.According to the principle of a great mass method,a great mass was added on the support.Based on the precise transfer matrix theory for frequency domain,the overall transfer relationship of structures was established.In addition,the Fourier spectrum of seismic acceleration was input,and the dynamic response of structures was solved according to the boundary conditions.The corresponding computation program was compiled,and the corresponding analysis on the examples was carried out.The computation results show that the proposed method is correct and efficient,and can be used for the seismic response analysis on structures.
