Outline of Final Research Achievements

Aiming at developing the real time prediction method of site amplification in wide area, nonlinear site response analysis, an existing geotechnical database and seismic strong motion records are combined on Microsoft Excel based program. Major achievement and issues are as follows: (1) Method of real time simulation of 1D site response analysis is developed. However, number of analysis is limited to one par a PC. (2) Results of 1D site response analysis conducted for Osaka plane showed difference on site amplification factor from existing ones. After those issues being solved, real time earthquake simulation in wide area shall be made.
