Install web stiffeners, blocking between members, and nail to supporting members as <br /> per manufacturers recommendations. <br /> LVL WOOD MEMBERS <br /> LVL members noted on drawings are engineered laminated veneer lumber as <br /> manufactured by the Trus-Joist MacMillan Corporation. Alternate at contractors option <br /> of design properties. <br /> Sizes shown on plan are actual. <br /> WOOD TRUSSES <br /> Responsibilities of the contractor, building designer, truss manufacturer, and truss <br /> designer shall follow the publication "WTCA 1-1995 Standard Responsibilities in the <br /> Design Process Involving Metal Plate Connected Wood Trusses." <br /> Truss supplier shall notify structural engineer on any proposed revisions made to the <br /> layout indicated on this plan. <br /> Verify allowable bearing locations for girder trusses with structural engineer prior to <br /> final design stage. Provide metal bearing enhancers as necessary to utilize stud <br /> columns shown on plan. <br /> All prefabricated wood trusses shall be furnished in accordance with designs prepared <br /> by a professional engineer registered in the State of Minnesota, using the design loads <br /> and span conditions indicated, including designing gable truss webs for perpendicular <br /> to face wind loads. <br /> Truss manufacturer shall provide a truss layout and certified truss drawings prior to <br /> beginning construction. <br /> Trusses shall be designed for top and bottom chord superimposed dead and live loads <br /> as indicated above. <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 1/360 of the span. <br /> Design trusses for top chord bearing or bottom chord bearing as shown in drawings. <br /> Truss configuration, pitch, overhang, etc. shall be indicated on architectural drawings. <br /> Spacing of roof and/or floor trusses shall not exceed 24" o.c. <br /> Lumber for wood trusses shall be in accordance with manufacturers recommendations. <br /> Truss manufacturer to provide girder trusses, hip jacks, step-down trusses, as required <br /> and designed to support all superimposed loads. Provide hip-sets, dormers, and <br /> piggy-back trusses as required. <br /> Truss manufacturer to specify if roof sheathing applied before placing "over-framing". <br /> Provide metal framing anchors at truss bearing to mechanically fasten truss to bearing <br /> wall or supporting 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 <br /> accordance with the truss manufacturer's design and directions. <br /> No cutting, notching, or modifications of trusses will be allowed without the <br /> manufacturer's written approval. <br /> Contractor shall provide permanent and temporary diagonal, lateral and cross bracing <br /> in accordance with the publication "HIB-91 Commentary and Recommendations for <br /> Handling, Installing and Bracing Metal Plate Connected Wood Trusses" by the Truss <br /> Plate Institute, and as otherwise necessary. For spans longer than 60ft., contractor <br /> shall hire a structural engineer to design bracing. <br /> The contractor shall provide permanent cross bracing in the plane of web members as <br /> shown on HIB—91 and as required by the truss designer. <br /> Permanent bottom chord bracing and web bracing shall be located as shown on the <br /> truss drawings and shall be minimum 2x4 with 2-16d nails to end walls and trusses, <br /> lapping 2 trusses spaces at splices. <br />
