In this paper, we report the results of static loading tests on traditional wooden two-storied frames with through columns. The tests target a frame with column reinforced with a stainless steel plate and a frame reinforced with an FMS alloy damper for the purpose of reinforcing the joints against fracture caused by the axial force and bending moment of beams “Sashigamoi”. We also propose a practical 2-dimensional FEM model that evaluates the behavior of the joint and the frame of the traditional wooden two-storied frames, and compare the analysis results with the experimental results.
