Response of RC Walls Subjected to Tsunami Debris Collision by Nonlinear Finite Element Analysis

摘要

An experimental and analytical investigation of the response characteristics of reinforced concrete structures subjected to a tsunami wave pressure and debris collision force was performed, as well as verification of the applicability of numerical analysis. Even if the response of the material remained within the elastic range after a single collision, we found that plasticizing by receiving repeated collision forces was possible. In addition, the nonlinear finite element analysis generally provided the experimental results such as the strain, residual displacement, and crack pattern of the reinforced concrete structure subject to wave pressure and collision force.
