To expand the use of JAS structural cedar lumber, basic data for the design of wooden trusses for medium-scale buildings made of lumber jointed by MPC was verified. As a result of tensile test of lumber from western Japan, it was confirmed that the lumber from any region performed satisfactorily compared with standard tensile strength and Young’s modulus. Furthermore, several variety connection tests were conducted to obtain the connector performance of two MPCs. As a result, strength performances for structural design were obtained for MPC types and each angle of lumber and MPC.
