Abstract
Building Research Institute (BRI) is operating a nationwide strong motion network. Total 75 stations are disposed in major cities throughout Japan. The observation project aims to contribute to advance in seismic design technology for buildings. Therefore seismic response of buildings is the main target of the observation. A great number of strong motion records have been obtained and utilized to study local site and geological effects, soil-structure interaction and dynamic behavior of buildings. The paper introduces outline of the BRI strong motion network and its recent topics.
