内容記述 |
To enhance the seismic performance of conventional post-and-beam timber houses commonly built in Japan, one must provide horizontal assemblies such as floors, ceilings, and roofs with sufficient in-plane shear resistance as well as a vertical assembly of shear walls. This study examined the shear resistance of timber floors and attic horizontal planes nail-jointed with structural particleboards (PBs). Floor joist system specimens and attic beam system specimens with a dimension of 1.82 m × 2.73 m were manufactured form JIS (Japanese industrial standard) 18M type PBs with thicknesses of 12 and 15 mm. The specimens were shear loaded under a cyclic mode until fracture. The effects of PB thicknesses, clearance gaps between PBs, nailing intervals, and nail types on the shear resistance were investigated. The results obtained are as follows.
Horizontal planes attached with a 15-mm-thick PB showed an initial stiffness somewhat higher than that with a 12-mm-thick PB, whereas the maximum bearing load and ultimate load did not change. A clearance gap of approximately 4 mm between PBs was found to slightly weaken the shear resistance, and the negative effect was larger at the floor joist system than at the attic beam system. Shortening a nail interval from 150 mm to 100 mm enhanced the shear resistance by approximately 20% and 30% for the floor joist system and the attic beam system, respectively. Changing the nail type from JIS N50 to JIS CN50 strengthened the shear resistance of the attic beam system by approximately 20%, whereas a clear positive effect was not recognized for the floor joist system. The shear resistance of floor joist and attic beam systems attached with PBs was found to be comparable to those attached with a structural plywood or an oriented strand board specified in the building code in Japan. |
