The roof structure is a system of "built on site" trusses, spaced on 24 inch <br />centers. The truss system is constructed of 2x4 members with nailed connections <br />using plywood gusset plates. I have evaluated the trusses and found that the individual <br />members are adequate to support the predictabie roof loads that are expected. <br />However, the nailed connections are not adequate and are in need of additional nails. <br />The end joints of the juncture of the ceiling joists and the rafters, immediately above the <br />supporting wails, must have no less than 50 8d nails in each member for a total of 100 <br />nails. 25 i �ails may be installed from one side and the other 25 from the opposite side. <br />Some additional gusset plate area may be needed to make a reasonable connection. <br />Other joints are not as heavily loaded and will require 40 8d nails in each member in the <br />joints. 20 nails may be instailed from each side. <br />This may seem like a significant amount of nailing. However, when compared to a <br />premanufactured truss with steel gussets, it is equal in structural integrity. <br />If I can be of further assistance in this matter, please call. <br />Sincerely yours, <br />Jack A. Swardz, P.E. <br />q i'�-°1� <br />
