The purpose of these calculations was to verify the slenderness ratio (1/r) of the 2" x 6" struts above the vaulted ` ceiling, and to determine the required connections (size and number of nails). A The subject struts were previously measured to be 8'-7" in length. As shown on the attached / calculations, the slenderness ratio of the struts is in excess of the maximum allowed value of 50. However, doubling these struts, which would be the simplest form of increasing the strength of the struts, reduces the slenderness ratio to 29, which is an acceptable value. in doubling the struts, the new lumber should be joined with the existing using 16d common nails, face nailedat 16 inches on-center. , r To determine the number of nails required for the end connections• the compressive force applied to each strut was first calculated as approximately 493 pounds. Using 10d common nails with a capacity of 90 pounds force each, the required number of nails was determined to be 6 per connection. Therefore, the new strut members should be attached to the purlin using three 10d nails, toenailed, per side. We appreciate the opportunity to assist you on this project.

At the time of our inspection the previously existing wood shake roof had been completely removed. The roof covering the northern one-half of the structure (2no story, over the bedroom areas) had been replaced with sub 6.0 pounds per square foot (psf) Monier Lifetile concrete roofing tiles. However, roof operations over the southern one-half of the house had been suspended pending the roof inspection. It was Technicon's understanding that the inspection was to include only the southern portion of the house, predominantly the vaulted ceiling area and stairwell. The term "roof truss" or "roof trusses", as used in this report pertains to the Our inspection consisted of a visual observation of the existing roof system, and evaluation of the system for conformance with applicable sections of the 1997 Uniform Building Code. The main trusses of the structure span approximately 24 feet 4 inches -(horizontal projection of 17 feet 4 inches) from the edge of the first story to the ridge above the second story. The measured ridge height above the second story portion of the residence was 4' 6". All roof trusses utilized 2" x 6" construction on 24" spacing with a maximum unbraced span of 8' 7" (horizontal projection of 6 feet 2 inches). The maximum tributary loaded area was determined to be approximately 49 square feet. Ceiling joists associated with the southernmost 201 story portion were 2" x 6" on 24" spacing. The maximum slope of the roof was determined to be approximately 8.56 inches vertical per 12 inches horizontal, or about 9/12. The portion of the roof above the northern half of the home was substantially flatter than the southern portion.. The unit loading of the previous wood shake roof was estimated at 8 pounds per square foot dead load (3 psf shingles + 1.5 psf Vx4" stripping + 1.5 psf felt + 2.0 psf top chord of truss) plus 16 psf live load (per Table 16-C 1997 UBC). The unit loading of the new tile roof is estimated at 12.5 pounds per square foot dead load (6 psf tile + 1.5 psf 1"x4" stripping + 1.5 psf felt + 1.5 psf plywood sheathing + 2.0 psf top chord of truss) plus 16 psf live load. Due to the 9/12 pitch of the roof, the roof dead load, for purposes of this evaluation, was increased by 10 percent to 13.75 psf. Assuming the 2" x 6" trusses were constructed using No. 2 Douglas Fir (typical for California). the trusses were assigned a design allowable bending stress (Fb) of 1,535 pounds per square inch (psi) and a modulus of elasticity (E) of 1,600,000 psi, per 1997 UBC Table 234V -V-1. Utilizing 1997 UBC Table 23 -IV -R-3 (LL = 20 psf + DL = 15 psf), a maximum allowable unbraced span of • 10 feet — 10 inches (horizontal projection) was determined for the 2" x 6" trusses with 24 inch spacing. 4539 N.

The increase in roof weight should not cause the existing lateral load conventional bracing to be exceeded. Furthermore, additional areas not previously inspected which are of similar construction, i.e., grade and size of lumber, spacing, and with a maximum allowable unbraced span less than that noted above, will also be suitable to support the subject increased loading conditions. Therefore, if it is determined that the remainder of the roof system is of similar We appreciate the opportunity to assist you on this project.
