Abstract

<p>Mechanical snubbers and inertial mass dampers are known as vibration control devices that have inertial mass elements and generate inertial resistance. By adding devices with inertial mass elements to piping systems, we aim to reduce various responses of piping systems during earthquakes. In this study, we optimize design parameters of a mechanical snubber installed on a single cross section beam (continuum model) piping system to achieve good dynamic responses of the beam while maintaining the structural integrity of the beam and mounting device. We confirmed that we could search for optimal design parameters, and found the effectiveness about using the device.</p>
