Abstract

In 2007, Round Robin Test (RRT) on ground response analyses has been conducted by the technical committee of Soil Dynamics and Geotechnical Earthquake Engineering of Korean Geotechnical Society. Total 14 teams have reported 16 different results. This paper discusses the evaluation of ground response dispersion caused by the difference of input ground motions. In order to determine the characteristics of ground response, this study analysed the peak ground acceleration, predominant period, and response spectrum of reported ground surface motions. The results suggest that ground response dispersion due to the difference of input ground motions can be significant.
