STRUCTURAL NOTES <br />CODE: 2018 International Building Code (IBC) <br />LIVE LOADS: <br />Roof - <br />LATERAL LOADS: <br />FOUNDATION: <br />25 psf (snow) <br />Wind: 85 mph, Exposure `B" <br />Seismic: Ss = 1.40 ; S 1 = .0.53; Sds = .931 <br />Soils Report Available: No <br />Design bearing pressure 1500 psf. Any Foundation elevations shown on the plans and <br />sections are estimated. All footings shall bear on undisturbed earth or compacted fill and <br />shall extend to firm bearing when poor bearing is encountered at elevations shown. <br />Compacted fill shall be well -graded granular fill with not more than 5% passing a #200 <br />sieve. Fill shall be placed in eight -inch maximum loose lifts and compacted to 95% <br />maximum dry density as determined by the compaction procedure in ASTM D-1557. <br />CONCRETE: <br />Unless noted otherwise on the plans, concrete f c shall be 2500 psi at 28 days. Minimum <br />of 5&1/2 sacks of cement per cubic yard of concrete, and a maximum of 6&3/4 gallons <br />of water per 94-pound sack of cement. A standard mix design satisfying the above <br />minimum strength is also acceptable. Provide mix design data to the engineer for review <br />and approval. <br />Add plastocrete or pozzolith in accordance with the manufacturer's recommendations to <br />all concrete except footings. Concrete protection for reinforcing: <br />Bottom of footings: 3" <br />Wall exposed to earth: 2" <br />Wall exposed to weather: 1 & 1 /2" <br />Wall inside face: 3/4" <br />All concrete in footings and walls, slabs and beams shall be poured in a monolithic pour <br />unless shown otherwise or approved by the structural engineer or record prior to pouring. <br />Aluminum conduit and accessories shall not be embedded in any concrete. <br />REINFORCING STEEL: <br />Deformed billet steel ASTM A-615, Grade 60, fs = 24,000 psi.unless noted otherwise o. <br />the plans. Lap all splices a minimum of 40 bar diameters. Provide elbow bars at wall <br />corners and intersections to splice horizontal bars. Provide two #5 bars around all <br />openings with a minimum dimension of eleven (11) inches or greater in walls and slabs. <br />Extend the bars 2'-0" beyond openings or as far as possible and hook. Provide one #5 X <br />\n <br />N <br />4'-0" center diagonal bar at corners. Any welded wire fabric (WWF) shall conform to <br />ASTM 185. WWF shall be lapped one crosswire plus two inches (i.e., 8" for 6X6 mesh). <br />A a <br />M <br />�" <br />°z <br />Reinforcing placing drawings shall be prepared by a qualified detailer in accordance with <br />Q <br />o <br />the —most current ACI detailing manual. Submit placing plans to the structural engineer of <br />record prior to fabrication. Any Grade 60 steel requiring bends shall be shop bent only <br />(preheating is required). Cold field bending is allowed only for Grade 40 rebar. <br />w o w <br />STRUCTURAL LUMBER & TIMBER: <br />All lumber shall be graded in accordance with current WWPA standard grading rules for <br />Western lumber. Use the following species and minimum grades unless noted otherwise <br />on the plans: <br />o <br />Studs and Columns: DFL Standard <br />Wall Plates & Screeds DFL Utility.. <br />0 <br />� w <br />Joists & Rafters DFL #2 <br />^' <br />Header & Flush Beams DFL #2 <br />a <br />4X Beams DFL #2Cj <br />6X Beams DFL #1 <br />v <br />iJ <br />ID <br />N� <br />3 <br />� <br />All plywood shall be APA C-D interior grade with exterior glue and a minimum panel <br />o <br />index of 42/20 for floors, 32/16 for the roof, and 16/0 for the walls. <br />V <br />ROOF SHEATHING: <br />U <br />All plywood shall be APA C-D interior grade with exterior glue and a minimum panel ID <br />N <br />Index of 32/16. Use 7/16" CDX plywood, unblocked, nailed to joists with 10d nails at <br />r <br />six (6) inches on center at all supported panel edges (edge nailing), and at twelve (12) <br />¢15 <br />V I <br />inches on center along intermediate framing members (field nailing). Notye: 7/16" OSB <br />A <br />U <br />U <br />U <br />OKO with same nailing pattern <br />>W <br />o <br />SPECIAL INSPECTION REQUIRED FOR: (as a minimum) <br />1. Any epoxied connections to existing concrete. I I .tea <br />MISCELLANEOUS: <br />�Z <br />Contractor shall verify all dimensions and conditions in the field. Verify the size and <br />location of all openings in the floor, roof and walls with architectural, mechanical and <br />electrical drawings. Provide temporary bracing as required until all permanent <br />connections and stiffeners have been installed. <br />
