EXPERIMENTAL STUDY ON SEISMIC PERFORMANCE OF REINFORCED MASONRY TRAIN PLATFORM

Abstract

 In past major earthquakes such as The 2011 off the Pacific coast of Tohoku Earthquake, the masonry train platform collapsed and underwent large deformation. As there are passengers to use the trains on the platform and the trains run close to the passengers, the occurrence of the collapse of the platform will affect the running safety of the train and may cause human damage. Therefore, we consider that the masonry structure platform needs to be reinforced to increase seismic performance. Therefore, we conducted a shaking table test of the model in the 1G field for the purpose of grasping the collapse mechanism at the time of earthquake and developing an efficient seismic reinforcement method. As a result from the experiment, we grasped the behavior leading to the collapse, proposed an efficient reinforcement method based on the behavior, and confirmed that the proposed method was effective as the seismic reinforcement method of the masonry train platforms.
