奥村組 has begun demonstration testing using an in-service seismically isolated building completed 40 years ago to verify changes in the performance of its seismic isolation devices. The company plans to use future measurements to assess changes in the devices’ behavior and reliability.
奥村組 will conduct demonstration testing on an in-service seismically isolated building that is reaching 40 years since completion, in order to verify changes in the performance of its seismic isolation devices. The aim is to obtain insights that can contribute to improving the reliability of current seismic isolation systems by observing the building’s behavior over an extended period.
The demonstration testing is scheduled to evaluate the damping characteristics of the seismic isolation devices and their behavior during earthquakes based on measured data. The objective is to clarify the actual nature of performance changes that are difficult to capture using conventional design indicators alone.
Through the publication of future results and additional data, a methodology for evaluating seismic isolation devices based on real-world examples may become more widespread.
