Structural health monitoring (SHM) is one of the most effective methods for estimating building damage immediately after an earthquake. However, this method generally requires the installation of expensive sensors in buildings, which makes it often difficult to implement and maintain. In this paper, a simple damage estimation method for RC buildings is proposed assuming next-generation gas meters are installed. Using time history response analyses, changes in the natural period of the building due to damage were evaluated using data from next-generation gas sensors, and the relationship between the changes in the natural period and the damage was developed.
