摘要：

This study demonstrates a method for seismic response evaluation of large-span cantilevered roofs excited by horizontal seismic input. Firstly we identified the vibration characteristics of an actual cantilevered roof by performing microtremor measurement. By analyzing the data, we found that the cantilevered roof had two major vertical vibration modes, the vibration of cantilever itself and the vibration exited by the sway deformation of the main building. When the main structure and cantilevered roof resonate, the response of cantilever increases. In this paper, the method for specifying that response characteristics of cantilevered roofs is discussed. © 2019 Architectural Institute of Japan. All rights reserved.
