<br />Design valid for use only with MiTek® connectors. This design is based only upon parameters shown, and is for an individual building component, not
<br />a truss system. Before use, the building designer must verify the applicability of design parameters and properly incorporate this design into the overall
<br />building design. Bracing indicated is to prevent buckling of individual truss web and/or chord members only. Additional temporary and permanent bracing
<br />is always required for stability and to prevent collapse with possible personal injury and property damage. For general guidance regarding the
<br />fabrication, storage, delivery, erection and bracing of trusses and truss systems, see ANSI/TPI1 Quality Criteria and DSB-22 available from Truss Plate Institute (www.tpinst.org)

<br />vertical left and right exposed;C-C for members and
<br />forces & MWFRS for reactions shown; Lumber
<br />DOL=1.60 plate grip DOL=1.60
<br />3) 100.0lb AC unit load placed on the bottom chord, 23-6-0

<br />4) This truss has been designed for a 10.0 psf bottom
<br />chord live load nonconcurrent with any other live loads.
<br />5) * This truss has been designed for a live load of 20.0psf
<br />on the bottom chord in all areas where a rectangle
<br />3-06-00 tall by 2-00-00 wide will fit between the bottom
<br />chord and any other members.
<br />6) Ceiling dead load (5.0 psf) on member(s). 21-23, 22-23
<br />7) Bottom chord live load (20.0 psf) and additional bottom
<br />chord dead load (20.0 psf) applied only to room. 16-17
<br />8) A plate rating reduction of 20% has been applied for the
<br />green lumber members.
<br />9) Bearings are assumed to be: , Joint 19 DF No.2 , Joint
<br />12 DF No.2 .
<br />10) Refer to girder(s) for truss to truss connections.
<br />11) Provide mechanical connection (by others) of truss to
<br />bearing plate capable of withstanding 83 lb uplift at joint
<br />19, 157 lb uplift at joint 12 and 101 lb uplift at joint 1.
<br />12) This truss has been designed for a moving concentrated
<br />load of 250.0lb live located at all mid panels and at all
<br />panel points along the Top Chord, nonconcurrent with
<br />any other live loads.
<br />13) Attic room checked for L/360 deflection.
