GENERAL NOTES: <br />1. DESIGNED IN ACCORDANCE WITH THE 2009 INTERNATIONAL BUILDING CODE. <br />2. ALUMINUM DESIGN IN ACCORDANCE WITH THE 2005 EDITION OF ALUMINUM ASSOCIATION'S <br />SPECIFICATIONS AND CHAPTER 20 OF THE INTERNATIONAL BUILDING CODE. <br />3.

ALL STRUCTURES DESCRIBED IN THIS <br />REPORT ARE DESIGNED USING PRESSURES CALCULATED FROM "3 SECOND GUST WIND SPEEDS". FOR <br />ATrACHED STRUCTURES THE MAXIMUM MEAN ROOF HEIGHT OF THE EXISTING STRUCTURE IS 30'. Kzt WAS <br />ASSUMED AS 1.0 FOR ALL WIND LOADS. SITE LOCATIONS REQUIRING HIGHER A HIGHER Kzt VALUE <br />(ISOLATED HILLS, RIDGES, ESCARPMENTS) WILL REQUIRE HIGHER WIND LOADS AS PER ASCE7-05 SECTION <br />6.5.7 AND ARE OUTSIDE THE SCOPE OF THIS REPORT. <br />NOTE: EXPOSURE B: SHALL APPLY WHEN THE GROUND SURFACE ROUGHNESS CATEGORY B (URBAN AND <br />SUBURBAN AREAS, WOODED AREAS, OR OTHER TERRAIN W/ NUMEROUS CLOSELY SPACED OBSTRUCTIONS <br />HAVING THE SIZE OF A SINGLE FAMILY DWELLING OR LARGER) PREVAILS IN THE UPWIND DIRECTION FOR A <br />DISTANCE OF AT LEAST 1500 FT. <br />EXPOSURE C: SHALL APPLY WHEN EXPOSURE B AND D (SMOOTH MUD FLATS, SALT FLATS, UNBROKEN ICE <br />AND OTHER) DO NOT. <br />SEISMIC LOADING <br />MAXIMUM Ss = 150% SHOWN IN 2009 IBC FIGURE 1613.5(1) <br />Ss > 150% ARE NOT REQUIRED AS PER ASCE7-05 12.8.1.3 <br />Sl NOT APPLICABLE TO THESE STRUCTURES <br />SITE CLASS = D <br />BASIC SEISMIC FORCE RESISTING SYSTEM <br />POSTS EMBEDDED INTO FOOTINGS =ORDINARY STEEL MOMENT FRAME >> R = 1.25 <br />POSTS SURFACE MOUNTED = GENERIC SYSTEM >> R= 1.25 <br />ANALYSIS PROCEDURE = EQUIVALENT LATERAL FORCE PROCEDURE <br />THESE ROOFS ARE NOT SUBJECT TO MAINTENANCE WORKERS AND HAVE NOT BEEN EVALUATED FOR A <br />CONCENTRATED 300 LBF LOAD. <br />THE BASIS OF THE DESIGN FORCES ARE IN ACCORDANCE WITH THE BASIC LOAD COMBINATIONS DESCRIBED <br />IN IBC SECTION 1605.3.1 AND NO FURTHER INCREASES ARE PERMITTED FOR PATIO COVERS RESISTING <br />WIND OR SEISMIC FORCES. <br />4. THIS ENTIRE ENGINEERING PACKAGE IS NOT REQUIRED FOR MOST BUILDING PERMITS, SUBMISSION FOR <br />A BUILDING PERMIT MUST INCLUDE: <br />a. GENERAL NOTES (2 PAGES) <br />b. STRUCTURAL CONFIGURATIONS (1 OR 2 PAGES) <br />c. RAFTER SPAN TABLES (FOR LATTICE STRUCTURES), PANEL SPAN TABLES FOR SOLID COVER <br />STRUCTURES) OR BOTH (FOR COMBINATION STRUCTURES) <br />d. HEADER POST SPACING, FOOTING SIZE AND POST TABLE FOR LIVE/SNOW AND WIND LOAD <br />e. ALL APPROPRIATE DETAILS <br />f. OTHER DOCUMENTATION REQUIRED BY LOCAL BUILDING AUTHORITY, <br />5. CONCRETE MIX: Fc=2500,3000 OR 3500 PSI FOR 28 DAYS IN NEGLIGIBLE, MODERATE, AND SEVERE <br />CONDITIONS AS SHOWN IN FIGURE 1904.3 OF THE 2009 IBC. PATIO STRUCTURES MAY BE ATrACHED TO <br />CONCRETE SLAB WITHOUT FOOTINGS WHEN THE POST LOAD IS 750# OR LESS AND THE FROST DEPTH IS <br />ZERO. CONCRETE SHALL BE A MINIMUM OF 3.5 INCHES THICK AND NO CRACKS WITHIN 2'-6" OF POSTS. <br />POSTS SHALL BE SET BACK A MINIMUM OF 4 INCHES FROM EDGE OR EXPANSION JOINT OF A SLAB. <br />6. FOOTINGS HAVE BEEN DESIGNED FOR CLASS 5 SOIL AS PER TABLE 1806.2. ALLOWABLE FOUNDATION <br />PRESSURE IS 1500 POUNDS PER SQUARE FOOT. LATERAL BEARING PRESSURE IS 100 PSF/F-TAND IS <br />DOUBLED PER BC SECTION 1806.3.4. THESE DESIGN VALUES DO NOT APPLY TO MUD, ORGANIC SILTS, <br />ORGANIC CLAYS, PEAT OR UNPREPARED FILLS AND MAY REQUIRE FURTHER SOIL INVESTIGAT]ON. THE <br />BUILDING OFFICIAL MAY ASSIGN A LOAD BEARING CAPACITY. UNITS IN SNOW/LIVE LOAD AREA OF 25 PSF <br />OR LESS MAY BE BUILT ON 1000 PSF BEARING SOIL W/O ADDITIONAL ENGINEERING. MINIMUM FOOTING <br />DEPTH IS THE LOCAL FROST DEPTH. <br />7. 20 PSF AND HIGHER LIVE LOAD STRUCTURES MAY BE USED AS COVERS FOR PARKING OF MOTOR <br />VEHICLES. CARPORTS MUST HAVE AT LEAST TWO OPEN SIDES AND HAVE FLOOR SURFACES MADE OF <br />APPROVED NONCOMBUSTIBLE MATERIAL OR ASPHALT. <br />8. AT LEAST ONE HORIZONTAL DIMENSION (PROJECTION OR WIDTH) OF COVER SHALL BE LESS THAN 30'. <br />9. ALL STEEL SHALL BE GALVANIZED ASTM A-653 G90, A123 G45 OR A153 B-3, PAINTED ASTM A755 OR USE <br />AN APPROVED COATING COMPLYING WITH IBC SECTION 2203.2. <br />10.
