1.Embedment is measured from the top of the framing member to the beginning of the tapered tip of the lag screw.
Embedment in sheathing or other material is not effective.The length of the tapered tip is not partof the embedment
length.
2.'Max.Trib Area'is the product of the'Max.Tributary Width'(along the rails)and 1/2 the panel width/height

Ratio Proposed Loading to Current Loading: BO% OK
The gravity loads in the area of the solar array are decreased;thus,the stresses of the
structural elements are decreased.Therefore,the requirements of Section 807.4 of the
2015 IEBC as referenced in 760 CMR Chapter 34,9th Edition are met and the structure
is permitted to remain unaltered.
