Abstract

<p>These days, there are a lot of high-rise buildings in Japan. These buildings don't vibrate so strongly with the short period earthquake, but they are weak for the long period earthquake. When a long period earthquake happens, they will vibrate in large amplitude and continue for long periods. So it is important to make buildings stronger to the long period earthquake. Most of these buildings already have some damping devices to reduce the vibration excited by wind, but these devices won't work effectively for earthquake. In this study, the effectiveness of the active brace added for each layer of the building which already has Tuned Mass Damper (TMD) is verified. After that, the optimal number of active braces and their places to set are discussed.</p>
