Abstract: This paper presents a numerical method, known as hybrid lattice particle modeling (HLPM), for the study of the reinforcement potential for coating of three-layer functionally designed nonlinear response retrofitting structure on a linear response infrastructure. The three nonlinear materials behave with different strengths as members of the three-layer retrofitting structure. Different arrangements of these three materials are attempted to obtain a good understanding of the intrinsic mechanism to reach an optimal reinforcement performance to the infrastructure. The ultimate application is aimed at the retrofitting of failing infrastructure.
