【摘要】:對比研究不同的人工地震加速度時程的計算方法,發(fā)現(xiàn)不同方法之間的主要差異在于初始時程的獲得方式,包括采用與設計響應譜相近的真實地震過程和基于通過響應譜與功率譜密度間近似關系的方法;诤笠环N方法,開發(fā)人工地震加速度時程計算程序。采用計算實例進行人工加速度時程計算,得到的人工時程具有良好的形態(tài)和統(tǒng)計特征參數(shù);人工時程響應譜與設計譜具有良好的相容性。
[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.
