This research aims to install a panel with solid wood board fitted to timber grid into a frame and apply it as a bearing wall. In this paper, shear loading tests of the frame are conducted. A new mechanical model of the frame and an equation for calculating shear strain of solid wood board are proposed by extending the results of Part 1. The important factors here were the gapping between the each element of the mechanical model and the dispersion of the shear strain. The newly proposed model accurately calculated the restoring force characteristics of the frame experiments.
