[Abstract]:Comparing and studying the different calculation methods of artificial seismic acceleration time history, it is found that the main difference among different methods lies in the way of obtaining the initial time history. It includes the real earthquake process which is similar to the designed response spectrum and the method based on the approximate relation between the pass response spectrum and the power spectral density. Based on the latter method, the artificial earthquake acceleration time history calculation program is developed. The artificial acceleration time history is calculated with an example, and the artificial time history has good morphological and statistical characteristic parameters, and the artificial time history response spectrum has good compatibility with the design spectrum.
