An experimental study on large deformation performances of wood houses considering the break of joints

Abstract

This paper attempts to clear large deformation behaviors of two story wooden frame houses and to predict large deformation behaviors of two story wooden frame houses from the summation of static performances of two story wooden frame walls that compose those houses. 4 types of wooden frame houses and walls are tested. The comparison of the results between two story wooden frame houses and the summation walls indicates, 1) until l/30∼ 1/25rad. deformation of 1st story, the summation of walls can predict structural performances of two story wooden frame houses without tire influence of joint type of the column or the existences of boards, 2) after l/25rad. deformation of .1st story, the structural performance of the summation of walls become different from that ones because failure modes of brace in walls is different from those of houses.
