EXPERIMENTAL STUDY ON SEISMIC PERFORMANCE OF MASONRY TRAIN PLATFORM WITE AUTOMATIC PLATFORM GATE

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. Therefore, we consider that the masonry train platform needs to be reinforced to increase seismic performance, and we are developing an efficient seismic reinforced method. On the other hand, we have not understood seismic performance for masonry train platform with automatic platform gate yet. Therefore, we conducted a shaking table test of the model in a 1G filed in order to investigate the seismic performance of the masonry train platform with automatic platform gate. As a result from the experiment, it was confirmed that the seismic performance of the platform with up the automatic platform gate than one without the automatic platform gate. In addition, a simple reinforcement method was proposed based on the behavior observed in the model experiment. As a result from experiments from the proposed method, improvement of seismic performance by reinforcement was confirmed.
