The purpose of this research is to develop a high strength bearing wall for the framework construction method using Japanese frame material and Japanese plywood. To achieve this, it is necessary to consider the combination, or balance, of plywood thickness, wood species, frame materials and type of nails. At first, single shear tests were performed on the nail joints, then the optimum combination was determined by modelling. After that, the performance of the walls was verified with in-plane shear tests using full-scale bearing walls. It was found that when the wall legs are joined to the ground with metal joints, a brittle fracture has occurred at the metal joint. Therefore, by changing the test method from the column fixed type to the tie rod type without using metal joints, column base breakage was prevented and the high strength performance of the shear wall itself was confirmed.
