<br />Check attachment of Support to Existing Structure for Wind Uplift - Cont'd
<br />where:
<br />Y = Distance between 2 lag screws
<br />X = 1.2"
<br />Y' = Moment arm to 1st lag screw
<br />X = 5.5"
<br />Design (Factored) Load at each support:
<br /> 3 psf + (0.6 x 29.7 psf) = 20.8 psf
<br />Moment due to Load = (20.8 psf x 11 sq. ft.) x 5.5 inches
<br />Determine allowable load per 5/16" lag screw w/ 3.25" embedment into wood below
<br />according to the 2018 NDS.
<br />W ' = W x Cd x Ct Table 10.3.1 2018 NDS
<br />where:
<br />W = 266 lbs / in. of embedment per Table 12.2a
<br />Cd = 1.6 per Table 2.3.2 of 2018 NDS
<br />Ct = 1.0 per Table 10.3.4 of 2018 NDS
<br />W ' = 266 lbs/ in. x 3.25 in. x 1.6 x 1.0 = 1,383 lbs > 1,048 lbs OK
<br />OK. Use Tile Hooks with (2) 5/16" x 4" Lag Screws
<br />with 3.25" min. embedment into wood, at 48" O.C.
<br />max, as per Plans to Manufacturer's instructions.
<br />Moment due to Load = 1,258 in-lb
<br />Load to lag screw = 1,258 in-lb / 1.2 in
<br />Load to lag screw = 1,048 lbs
