Elasto-plastic response analysis of pipe systems including the pipe supports is necessary to evaluate the seismic fragility for input seismic motions exceeding the design assumptions. However, the elasto-plastic response analysis method for pipe supports has not been developed yet. In this study, we aim to develop the elasto-plastic response analysis method for pipe supports by focusing on the non-linearity of the load-displacement characteristics. We also conduct parametric analyses on the material properties, etc., for existing loading tests. This paper reports the quantitative computing for energy dissipation with the load-displacement characteristic curves obtained via the analyses, and the comparison between the analytic results and experimental results.
