Abstract
<p> In this paper, we investigated the bulging vibration characteristics of non-earthquake resistant FRP water tanks that were manufactured before the seismic design standard for tanks was established in 1980 and developed damping device against bulging vibration. We carried out vibration experiment using a non-earthquake resistant tank. The damping device was attached to corner of the tank, because bulging vibration cause damage particularly to there. As a result, it was found that by damping device, deformation of the tank’s panel was decreased. In addition, we confirmed damping effect, reducing repeated occurrence of large displacements and large accelerations to the tank by performing rainflow analysis.</p>
