Abstract | This report presents the results of 53 fire resistance experiments conducted on full-scale floor assemblies as part of the collaborative industry-government research program investigating the effects of frame member type, frame member depth (solid wood joist), frame member spacing, wood I-joist type, parallel-chord wood truss size, parallel-chord wood truss orientation, parallel-chord wood truss web type, parallel-chord wood truss connection type, insulation type, insulation in floor cavity (none, partial and full cavity), insulation support (steel mesh), sub-floor deck type, number of sub-floor layers, number of Type X gypsum board ceiling layers, number of Type X gypsum board ceiling layers vs number of sub-floor layers, sub-floor topping, resilient channel installation, resilient channel spacing, load magnitude and test repeatability as well as assemblies with unique design. |
