Abstract

There is a plan to install MEMS accelerometers into many structures such as houses, road signs, etc. These sensors are able to observe a seismic response. Therefore, it might be a realistic idea to build a super high-density seismic network system by compiling the seismic data measured by the MEMS accelerometers into a database. However, it has a problem to treat a structural response as a seismic data because the structural response has relatively larger intensity than the ground motion. In this paper, the estimation method for the SI (Spectral Intensity) calculated from a structural response is examined. In this method, a transfer function between a structural response and a gournd motion is estimated based on a single degree-of-freedom system. The SI-value is estimated using the ground motion calculated from the structural response using the transfer function. A numerical simulation shows that the SI values estimated from a structural response has good agreement with the value estimated from the original ground motion.
