Abstract
To prevent the stone wall structure from collapsing by an earthquake, it is indispensable to grasp the anti-seismic performance and enforce the wall by retrofitting if necessary. In this study, the authors has conducted an analysis of seismic response of historic stone wall structure and examined the retrofitting method based on the Two-dimensional Extended Distinct Element Method.
As a result, the anchor-reinforcement method was selected as an anti-seismic reinforcement, for its minimum intervention and visual impact to the historical stone wall. By comparing the movement of the wall with or without anchor reinforcement and recognizing the pattern by various applications, the study indicated the necessity of anti-seismic reinforcement as well as the tendency of response behavioral change and examined the validity of anchor reinforcement.
