伝統木造建物における込栓接合部ほぞ引抜降伏耐力の評価精度向上に関する研究

Abstract

We conducted pull-out experiments on test pieces that imitated "komisen" joints of traditional wooden buildings and examined the fracture mechanism and conducted material tests on the test piece sets based on the fracture mode observed in the pull-out experiment to obtain basic data on the material properties. In addition, we evaluated the yield strength by the existing EYT formula and compared with the experimental results, and considered the applicability of the existing formula. Also, we constructed two-dimensional FEM models that simulate the pull-out fracture of the joints and compared the experimental results with the analysis results.
