Following the large 5 storey Midply building project that MLIT* awarded last year, another PFC project that features the use of Midply was selected as a winner of the same innovative wooden building design award competition for this year. This year’s winner is a 6-storey demonstration project with the total floor area of 274 m2, the first 6-storey wooden building to be achieved in Japan. The demonstration structure will be built on the site of the Building Research Institute (BRI) in Tsukuba City. The Midply Wall System will be adopted as the lateral load resistive diaphragm for the partition walls on the 1st and 2nd floor levels. As 1-hour fire resistive structures are applicable only up to 4-storey buildings, this 6-storey project requires 2-hour fire resistive performance. Therefore, the dead load calculation was conducted assuming the material mass for the 2-hour fire resistive assemblies. COFI and the Japan 2×4 Home Builders Association is working on obtaining the 2-hour ministerial fire resistive approvals for these assemblies by July of this year. This demonstration project is to showcase the seismic and fire resistive technologies required for 6-storey PFC buildings. The BRI and the Japan 2×4 Home Builders Association have established testing and designing working groups to jointly conduct research on this project in order to better understand the design, installation and various performances of midrise wooden structures. Construction is expecting to begin in August this year and will complete in February, 2016.
