Existing Snow Load: 0.0 psf o�q 4 y; � .•60'
Existing Roof Live Load: 20.0 psf Lr,
Proposed Roof Live Load: 20.0 psf
Wind Load:Using CBC 2016(ASCE 7-10),Components and Cladding, Part 2: Low Rise Buildings(Simplified),the
following wind pressures were calculated.
pnet=X(Kzt) (pnet30)= 14.101-39.40 psf
X= 1.21
Kzt= 1.00
pnet30= 1-11.651-32.56' (Roof pitch=20 deg,Zone=2,Aeff= 21.1 sf,V=,110 mph)
Lag Bolt Capacity:
5/16" lag bolt capacity=270 lbs per inch embedment
With 2 1/2" minimum embedment,capacity=675 lbs
Required Capacity:
39.40 psf* 16 modules* 21.1 sf= 13300.6 lbs
13300.6 lbs/ 30 lag bolt connections= 443.4 lbs
The pull-out capacity of the 5/16" lag bolts with a minimum 2 1/2" embedment into the roof rafter is sufficient
to meet the demand of the wind uplift force on the solar system.
Seismic Load: Per Section 3403A.4 of the CBC 2016, if the demand-capacity ratio of the lateral load-carrying
elements increases less than 10%due to the addition of the solar system,no special provisions or structural
modifications are required.
Existing Roof Weight= 10.0 psf* 2295 sf= 22950 lbs
Weight of Solar System= 16 modules* r 52.6 lbs+ 169 lbs of racking= 1010 lbs
1010 lbs/ 22950 lbs= 0.04
The increase in load from the solar system will not increase the demand-capacity ratio of the existing lateral
load-carrying elements by over 10%.
