DESIGN LOADS
<br />LIVE LOADS: Live loads are determined in accordance with ASCE Ch. 7
<br />L = 40 PSI- (Residential)
<br />SNOW LOADS- Snow loads are determined in accordance with ASCE Ch. 7 with the following
<br />Factors:
<br />Ground Snow Load Pg = 20 psf Ct = 1.0 Ce = 1.0
<br />Roof Snow Load Ps = 25 psf Is = 1.0
<br />WIND LOADS: Wind loads are based on ASCE 7-10 Ch. 28 (Envelope Procedure) with the following
<br />factors:
<br />Exposure Category = B 1w = 1.0
<br />Velocity (3 sec) =110 mph (uit) Kzt = 1.0
<br />Design wind pressured for determining forces on components and cladding are determined in
<br />accordance with ASCE 7-10 Chapter 30.
<br />SEISMIC LOADS: Seismic loads are based on the Equivalent Lateral Force Procedure in ASCE 7-10
<br />Section 12.8 with the following factors:
<br />Risk Category = II Ss = 1.26
<br />Site Class = 0 S1 = 0.494
<br />Design Category = D SDS = 0.841
<br />R = 6.5 (wood shear wall) SD1 = 0.496

<br />PREMANURACTURED OPEN WEB WOOD TRUSSES: Trusses shall be design by a Structural Engineer
<br />licensed in the State of Washington, who is regularly engaged in the design of plate -connected
<br />wood trusses. Truss design shall be accordance with IBC Section 2303.4.
<br />Trusses shelf be design for the following dead loads:
<br />to chord bottom chord total
<br />roof trusses 10 psf 5 psf 15 psf
<br />In addition to dead loads, the design shall include the live, wind, snow loads as identified in the
<br />"Design Loads" section of these drawings, and the snow drift, sliding and unbalanced bads per
<br />ASCE7 Chapter 7. The truss design shall include concentrated and axial loads shown on framing
<br />plans and hanger schedules in these drawings.
<br />Roof trusses shall be designed for wind net uplift of 10 psf unless otherwise noted on the drawings.
<br />Trusses shall be fabricated by a manufacturer who is a member of the Truss Plate Institute, Trusses
<br />shall be supplied with the proper hangers, end connections, bridging, bracing to provide lateral
<br />stability of all truss members, and tie -down connections to beams and tops of walls. Trusses shall
<br />be supplied with tapered hardwood shimming so that every chord bears on the full width of every
<br />support, without notching the truss members. The truss manufacturer is responsible for ensuring
<br />the bearing seat does not exceed the sill plate capacity of the supporting element.
