Lumber design values are in accordance with ANSI/TPI 1 section 6.3 These truss designs rely on lumber values established by others. Pages or sheets covered by this seal: R78732448 thru R78732449 Madison Jr. High Classrooms Hernandez, Marcos October 5,2023 The truss drawing(s) referenced below have been prepared by MiTek USA, Inc. under my direct supervision based on the parameters provided by Sunpro Corporation (Lindon, UT). Re: IMPORTANT NOTE: The seal on these truss component designs is a certification that the engineer named is licensed in the jurisdiction(s) identified and that the designs comply with ANSI/TPI 1. These designs are based upon parameters shown (e.g., loads, supports, dimensions, shapes and design codes), which were given to MiTek or TRENCO. Any project specific information included is for MiTek's or TRENCO's customers file reference purpose only, and was not taken into account in the preparation of these designs. MiTek or TRENCO has not independently verified the applicability of the design parameters or the designs for any particular building. Before use, the building designer should verify applicability of design parameters and properly incorporate these designs into the overall building design per ANSI/TPI 1, Chapter 2. 400 Sunrise Ave., Suite 270 Roseville, CA 95661 916.755.3571 / MiTek-US.com Design valid for use only with MiTek® connectors. This design is based only upon parameters shown, and is for an individual building component, not a truss system. Before use, the building designer must verify the applicability of design parameters and properly incorporate this design into the overall building design. Bracing indicated is to prevent buckling of individual truss web and/or chord members only. Additional temporary and permanent bracing is always required for stability and to prevent collapse with possible personal injury and property damage. For general guidance regarding the 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) BCSI Building Component Safety Information WARNING - Verify design parameters and READ NOTES ON THIS AND INCLUDED MITEK REFERENCE PAGE MII-7473 rev. 1/2/2023 BEFORE USE. and available from the Structural Building Component Association (www.sbcscomponents.com) =6x8 =5x8 =5x6 =M18AHS 7x10 =6x6 =3x4 =3x4 =M18AHS 6x12 =5x6 =4x4 =3x8 =5x6 =1.5x4 16 15 14 13 12 11 109 18 1 19 2 3 4 5 6 20 78 17 0-5-8 0-5-8 0-3-8 33-11-14 5-5-0 28-1-10 5-5-0 5-10 -8 5-5-0 17-0-1 5-6-12 33-8-6 5-8-8 22-8-9 5-8-8 11-7-1 0-3-8 33-11-14 0-5-8 0-5-8 5-5-0 11-3-9 5-5-0 22-5-1 5-5-0 5-10 -8 5-6-12 33-8-6 5-8-8 28-1-10 5-8-8 17-0-1 5-0-0 4-0-2 3-0-0 0-11 -14 2-0-2 3-0-0 2-0-0 5-0-0 Scale = 1:63.6 Plate Offsets (X, Y):[1:0-4-12,0-3-4], [3:0-3-0,Edge], [5:0-3-0,0-3-4], [6:0-3-8,0-1-8], [10:0-3-0,0-3-4], [12:0-6-0,Edge], [14:0-4-12,Edge], [15:0-3-0,0-2-8] Loading (psf)Spacing 2-0-0 CSI DEFL in (loc)l/defl L/d PLATES GRIP TCLL 40.0 Plate Grip DOL 1.15 TC 0.87 Vert(LL)-0.61 13 >647 240 MT20 220/195 (Roof Snow = 40.0)Lumber DOL 1.15 BC 0.84 Vert(CT)-0.92 13 >431 180 M18AHS 169/162 TCDL 12.0 Rep Stress Incr YES WB 0.97 Horz(CT)0.19 10 n/a n/a BCLL 0.0 *Code IRC2018/TPI2014 Matrix-AS BCDL 8.0 Weight: 169 lb FT = 20% LUMBER TOP CHORD 2x4 DF No.2 *Except* 3-5:2x4 DF 1800F 1.6E BOT CHORD 2x4 DF 1800F 1.6E *Except* 14-16:2x4 DF No.2 WEBS 2x4 DF Stud *Except* 15-1,16-1:2x4 DF No.2, 17-18:2x6 DF No.2 BRACING TOP CHORD 2-0-0 oc purlins (2-1-4 max.): 1-8, 1-17, except end verticals.
