On the evaluation of seismic design margin of the piping and support system in the nuclear power plant, the elasto-plastic behavior of support has played the important role in the seismic response analysis. It is desirable to establish the simple and effective non-linear modeling of the support in order to conduct the seismic response analysis considering each elasto-plastic characteristics of actual numerous supports in the piping system. In this study, the simplified modeling methodology related to the elasto-plastic behavior of the support was investigated by classifying the several non-linear types by estimating the limit load capacity of support, in which the results of non-linear type classification and accompanied failure mode were compared to the static loading tests of the support. At the results, methodology to identify the non-linear type of the support with normal bi-linear model was proposed, and it was confirmed that the non-linearity of the support was classified into the five different types.
