        The arched stone bridge has been continuously deteriorated and damaged by the weathering and corrosion over time, and also natural disaster such as earthquake has added the damage. However, masonry stone bridge has the behavior characteristics as discontinuum structure and is very vulnerable to lateral load such as earthquake. So, it is necessary to analyze the dynamic behavior characteristics according to various design variables of arched stone bridge under seismic loads. To this end, the arched stone bridge can be classified according to arch types, and then the discrete element method is applied for the structural modelling and analysis. In addition, seismic loads according to return periods are generated and the dynamic analysis considering the discontinuity characteristics is carried out. Finally, the dynamic behavior characteristics are evaluated through the structural safety estimation for slip condition.

        In this study, we propose a structural modeling method to analyze the seismic behavior characteristics of arched stone bridge. For this purpose, we select the representative model of arched stone bridge, and various arch types are set in consideration of the width and height. Accordingly, this study applies the discrete element method for the modelling of discontinuum structure to analyze the seismic behavior characteristics according to the various arched types.
