Study on Evaluation Method of Reinforcement Effect of Dry Masonry in Historical Monuments Applying DDA

In this paper, we propose a method for an evaluation method of reinforcement effect of dry masonry in historical monuments applying DDA, which is one of the discrete mechanics methods, to evaluate structural performance and to design effective countermeasures. In DDA analysis methods, we developed a method to evaluate the capacity load after reinforcement of dry masonry by incorporating a spring of the reinforcement member, and verified the reinforcement effect using this method. From the numerical analysis, it was confirmed that the results differ depending on the installation location, and these parameters affect the performance. It is important that the masonry construction of dry masonry has an influence on the collapsing mode and capacity load, and it is thought that the non-linear collapsing phenomenon is well simulated by our proposed method. As the result, we tried to propose an evaluation function to verify the reinforcement effect due to the difference in the reinforcement method.
