(208) 359-0740 0800239 Melaleuca Remodel -Truss Repair Per your request I have evaluated the top hung roof rafters (26" deep "I" with steel web with DF 2x4 top and bottom chords) spaced at 48" o.c. and spanning 30 feet using a snow load of 35 psf and a dead load of 15 psf. In addition to hand calculations, I have sized TJI open web rafters to get a rough idea of the required size of the bottom and top chords. The TJI software sizes the top and bottom chords at 1.5"x 8.5. The software does not indicated whether the chords are 2x Doug fir or other material. However, based on the ratio of the area of the existing (1.5x3.5) and that required by the TJ software (1.5x8.5) and assuming that the TJI software is using Doug Fir it appears that the roof has a snow load capacity of about 14.5 psf instead of the 35 psf required. Based on my calculations a snow load of 35 psf and a dead load of 15 psf requires that the roof trusses be reinforced as noted below. Reinforcing shall start five feet from each end. Apply %2" OSB to each side of each rafter from the top of the top chord to the bottom of the bottom chord. Attach the OSB using 16gauge 1 %2" staples with a 7/16" crown spaced at 2" o.c. The OSB shall be glued to the chords of the rafters prior to stapling. In as much as reinforcing is required to start so near the supports, it is my recommendation that all trusses be reinforced for the entire length of the truss. Please call if you have any further questions. Respectfully, Mv �S;coAttA' Spaulding, Design Intelligence LLC
