The National Institute of Forest Science performed a seismic test on the Midply Shearwall System on July 28. For the test, a Midply Shearwall bearing wall was constructed and vibration was applied at a vertical load of 3.7 tons in order to examine and study the seismic performance of the structure. The outcomes of the studies on this test may help the revision of the seismic design criteria for wood frame construction in the future.

The Midply Shearwall System is a new type of shear wall that was first co-developed by FPInnovations and the University of British Columbia in Canada in the 1990’s. This structure was included in the CSA O86 standards of Canada in 2014, and Canada Wood Japan has already developed the Midply Wall System Manual and commercialized and used the structure. This year, Canada Wood Korea is planning to translate the Japanese manual into Korean and introduce it through booklets and seismic design workshops in coming September and November.
