2 Single Spans INCLUDES TG Set Back 2.4m Maximum 40 kg/m 2 90 kg/m 2 TG Set Back 3.6m Maximum 40 kg/m 2 90 kg/m 2 Restraint value for slenderness calculations is 600 mm. K6 factor of 1.0 used. K23 factor applied to bending strength. J2 value of 1.5 used for DL Deflection. Pre-camber radius of 0m used. Roof Pitch of 25.0 deg used in load calculations. N3 WIND AREAS Downdrag loads were ignored. Total Uplift coefficient was 1.6 Deflection Criteria: 1: Dead Load = Span / 300 or maximum 9 mm. 2: Roof Live Load = Span / 250 or maximum 9 mm. 3: Wind Uplift = Span / 150. Timber Properties: Fb = 11 MPa, Elasticity = MPa Density = 600 kg/m3, Fs = 1.25 MPa Ft = 5.2 MPa, Fc = 11 MPa. Load Cases: 1: Dead Load 2: Roof Live Load 3: Wind Uplift MAX ROOF PITCH = 25 DEGREES Roof pitch used in calculations is 25 degrees. For roof pitches greater than 25 degrees but not exceeding 45 degrees you may multiply roof load width x 1.28 then use answer to enter table at correct load width. 64
