Correlation of Site Characteristic Period with Predominant Period of Ground Acceleration by a Simplified Model

摘要：

　　Site characteristic period is an important index in seismic zonantion and seismic resistance design.The characteristics of the ground motions are conceptually related with site characteristics.A simplified single-layer model is used for simulating horizontal strata under seismic loading to calibrate the correlation of site characteristic period with the predominant period of ground motion.The analytical results show that the inputted motions were amplified considerably by the site typically for the period components which were close to the site characteristic periods; with the shear wave velocity of the soil layer decreases with respect to the initial shear wave velocity,the predominant period of ground motion increases; the site characteristic periods are consistent with the predominant periods of the ground motion.
