| Abstract: | In this thesis,in view of the problem that current seismic design response spectra are only applicable to a range of natural period of structures less than 3s,a methodology is developed to calculate the probability-consistent long-period response spectra on the basis of Fourier spectral ratio of long period microtremor directly. Expressions for the direct calculation of probability-consistent long period response spectra by means of the measurement results of long-period mi-crotremor-Fourier spectral ratio are established. |
