This paper attempts to predict analytically large deformation static behaviors of two story wooden frame walls from the static performances of members and joints which compose wooden frame houses and walls. Wooden frame walls in this study have fragile joints which need to consider repeated contact problems, therefore extended distinct element method (EDEM) are applied which can consider these problems. 110 joint specimens are tested. They are pressed in axial side, bent inside and outside. From the results of these tests and the past researches, the two story wooden frame walls are modeled. Especially, because of the brace failure modes of pressing side, four kinds of models are proposed for each wooden frame wall. The comparison of the results between EDEM analyses and tests indicates, 1)in the range of assumed brace failure mode, proposed models can predict test results, 2)by considering brace models in detail, proposed models can reproduce test results precisely.
