Provide metal <br /> bearing enhancers as necessary to uti�ize stud columns shown on plan. <br /> Trusses shall be designed for top and bottom chord superimposed dead and live loads as indicated <br /> above. <br /> Truss supplier shall design trusses to support additional dead load from,but not limited to piping, <br /> ductwork, etc. Coordinate with mechanical/electrical as required. General contractor to verify location <br /> and magnitude of all such loads with truss supplier prior to fabrication of trusses. <br /> Coordinate any draft stop locations and design trusses accordingly. <br /> Live load deflection of roof trusses shall be limited to 1/240 of the span. <br /> Live load deflection of floor trusses shall be limited to 1/480 of the span. <br /> Design trusses for bearing as shown on drawings. <br /> Truss configuration,pitch,overhang, etc.shall be indicated on the architectural drawings. <br /> Spacing of roof trusses shall not exceed 24"o.c. <br /> Spacing of floor trusses shall not exceed 19.2"o.c. <br /> Lumber for wood trusses shall be in accordance with manufacturer's recommendations. <br /> Truss manufacturer to provide girder trusses, hip jacks, and step-down trusses as required and designed <br /> to support all superimposed loads. Provide hip-sets, dormers, and piggy-back trusses as required. <br /> Truss manufacturer to specify if roof sheathing needs to be applied before placing "over-framing". <br /> Provide metat framing anchors at truss bearing to mechanically fasten truss to bearing wall or supporting <br /> member as shown in details. <br /> Truss manufacturer shall provide truss to truss connection hangers. <br /> Bridging, and bracing of truss compression and tension members, shall be installed in accordance with <br /> the truss manufacturer's design and directions. <br /> No cutting, notching, or modifications of trusses will be allowed without the manufacturer's written <br /> approval. <br /> Contractor shall provide permanent and temporary diagonal, lateral, and cross bracing in accordance with <br /> the publication "BCSI 1-03 Building Component Safety Information, Guide to Good Practice for Handling, <br /> Installing and Bracing of Metal Plate Connected Wood Trusses" by the Truss Plate Institute and Wood <br /> Truss Council of America and as otherwise necessary. <br /> Permanent bottom chord bracing and web bracing shall be located as shown on the truss drawings and <br /> shall be minimum 2 x 4 with 2- 16d nails to end walls and trusses, lapping two truss spaces at splices. <br /> WALL SHEATHING <br /> Wall sheathing shall be minimum 15/32"thick APA rated panels, rated for spacing of supporting <br /> members. A minimum 32/16 span rating is recommended. <br /> Provide Exterior or Exposure 1 grade. Panels shall be continuous over two or more spans, and long <br /> dimension of panel shall be either perpendicular or parallel to supports. Fasten wall sheathing with 8d <br /> nails (.131"diameter x 2 1/2") spaced at 4" o.c. at supported edges and 8" o.c. at intermediate supports. <br /> Leave an 1/8"gap at all end and edge joints to allow for expansion. Stagger end joints of panels. Refer <br /> to plan and notes for any special shear walt nailing and bolting conditions. Gypsum sheathing to be a <br /> minimum of 1/2"thick fastened with 6d cooler or wallboard nails at 7" o.c. to all framing members unless <br /> noted otherwise. <br /> ROOF SHEATHING <br /> Roof sheathing shall be minimum 19/32"thick APA rated panels, rated for spacing of supporting <br /> members. A minimum of 40/20 span rating is recommended. Provide panel clips, one between each <br /> support, for supports spaced greater than 16"o.c. <br /> Appendix A,Highwood Road Residence,23Jan2013,MMY#: 13042.00,APG <br /> Page 5 <br />
