PRESSURES HEREIN ARE CALCULATED IN CONFORMANCE WITH (ASD) "ALLOWABLE STRESS DESIGN METHODOLOGY" PER IBC (2018) / FBC (2020) SECTION 1605 & ASCE 7-16 SECTION 2.4.1, WITH WIND PRESSURES PER ASCE CHAPTER 30, AND LOADING CONDITIONS USING THE CODES & CRITERIA AS OUTLINED. 2. 'WORST CASE' CRITICAL CONDITIONS SHALL BE ASSUMED FOR SAFE PRESSURE RATINGS. 3. TOPOGRAPHIC FACTOR Kzt=1.0 FOR FLAT TERRAIN USE ONLY. NO HILLS SHALL BE NEARBY AREA. 4. VERIFY USE OF Kd (DIRECTIONALITY FACTOR) WITH LOCAL BUILDING DEPARTMENT, Kd=0.85 USED HEREIN. PRESSURES SHALL BE ADJUSTED AS REQUIRED BY USE OF ALTERNATE Kd VALUES. GENERAL NOTES 5. THIS DOCUMENT IS NOT A SITE-SPECIFIC DOCUMENT & DOES NOT PERTAIN TO ANY SPECIFIC RESIDENCE. 6. THIS DOCUMENT IS ONLY VALID WITH AN ORIGINAL SIGNATURE & RAISED SEAL OR DIGITALLY SEALED. 7. THIS DOCUMENT ILLUSTRATES ALLOWABLE DESIGN WIND PRESSURES (ASD) AS LISTED. APPLICATION OF THESE TABLES AND CORRESPONDING WIND VELOCITY (SPEED), EXPOSURE, & OTHER COEFFICIENTS LISTED HEREIN SHALL BE DICTATED AND VERIFIED BY THE GOVERNING BUILDING DEPARTMENT AND PERMIT HOLDER. 8. NO WARRANTY FOR APPLICABILITY OF THE USE OF THESE TABLES IS OFFERED HEREIN. 9. THIS SPECIFICATION DOES NOT OFFER ANY PRODUCT APPROVED CERTIFICATION. REFER TO ANY SEPARATELY SUBMITTED TEST CRITERIA AND OTHER APPROVALS FOR DESIGN & INSTALLATION INFORMATION AND APPLICABILITY OF THESE TABLE VALUES WHICH IS TO BE VERIFIED BY OTHERS IN ACCORDANCE WITH GOVERNING CODES. 10. CONTRACTOR SHALL INVESTIGATE AND CONFORM TO ALL LOCAL BUILDING CODE AMENDMENTS WHICH MAY APPLY. 11. IT IS RECOMMENDED THAT A LICENSED ENGINEER OR REGISTERED ARCHITECT PREPARE SITE SPECIFIC DOCUMENTS FOR USE IN CONJUNCTION WITH THIS DOCUMENT. SEPARATE 'SITE-SPECIFIC' SEALED ENGINEERING IS REQUIRED IN ORDER TO DEVIATE FROM LOADS OR CONFIGURATIONS CONTAINED HEREIN. CONTACT THIS ENGINEER OR A LICENSED PROFESSIONAL FOR ALTERNATE CONFIGURATION CALCULATIONS AS MAY BE REQUIRED. 12. THE CONTRACTOR SHALL CAREFULLY CONSIDER POSSIBLE IMPOSING LOADS ON ROOF, INCLUDING BUT NOT LIMITED TO ANY CONCENTRATED LOADS WHICH MAY JUSTIFY GREATER DESIGN CRITERIA. ADDITIONAL ROOF LOAD CRITERIA SHALL BE PROPERLY ANALYZED BY A PROFESSIONAL ENGINEER. RESULTS ARE WIND ONLY. 13. EXCEPT AS EXPRESSLY PROVIDED HEREIN, NO ADDITIONAL CERTIFICATIONS OR AFFIRMATIONS ARE INTENDED. 14. ALTERATIONS, ADDITIONS OR OTHER MARKINGS TO THIS DOCUMENT ARE NOT PERMITTED AND INVALIDATE OUR CERTIFICATION. DESIGN LOAD COMBINATION CONDITIONS PRESSURES PROVIDED IN THE TABLES HEREIN ARE ALLOWABLE STRESS DESIGN FACTORED LOAD COMBINATIONS PER ASCE 7-16 CHAPTER 2.4 & CORRESPONDING WIND PRESSURE DESIGN CHAPTERS. THE WIND PRESSURES UTILIZED IN THESE CALCULATIONS ASSUME A CANOPY OF HEIGHT = 12FT AND AN AREA OF 100 SQFT. ASD LOAD COMBINATIONS HEREIN ASSUME A CONSTANT DEAD LOAD OF 2 PSF, ROOF LIVE LOAD, LR = 20 PSF, SNOW LOAD, S = 20 PSF, AND WIND LOAD, W AS CALCULATED FOR THE SELECTED STRUCTURE & SITE SPECIFIC CONDITIONS. PRESSURES LISTED ARE VALID FOR DESIGN CONDITIONS EQUAL TO OR LESS THAN THE LOAD COMBINATION CONSIDERED. FOR LOADING CONDITIONS EXCEEDING THE CONSTANTS STATED ABOVE (SUCH AS A ROOF OR SNOW LOADING EXCEEDING 20 PSF, OR THE CONSIDERATION OF SEISMIC LOADING), USE THE ONLINE LOAD COMBINATION TOOLS FOUND AT THE QR CODE PROVIDED. INSTRUCTIONS FOR TABLE USE: 1. IDENTIFY THE LOCAL VULT WIND VELOCITY BASED ON 3 SECOND GUST FACTOR FROM BUILDING DEPT OR PUBLISHED DATA. REFERENCED STANDARD WIND INFORMATION CAN BE FOUND AT HAZARDS.ATCOUNCIL.ORG AND AT THE QR CODE BELOW 2. CONFIRM THAT THE SITE-SPECIFIC & LOCAL MUNICIPALITY DESIGN CONDITIONS ARE WITHIN THE LIMITATIONS OF THIS MASTER PLAN AS STATED ABOVE. CONFIRM THAT THESE CONDITIONS ALSO COMPLY WITH LOCAL CODE REQUIREMENTS 3. IDENTIFY THAT THE STRUCTURE TO BE USED CONFORMS TO THE LIMITATIONS NOTED HEREIN. THIS DOCUMENT PROVIDES INFORMATION FOR OPEN-WALLED STRUCTURES THAT ARE EITHER FREESTANDING OR HOST-ATTACHED, AND HAVE A ROOF THAT IS AT LEAST 50% POROUS. 4. READ OFF POSITIVE (DOWNWARD), NEGATIVE (UPLIFT), AND LATERAL PRESSURES AS ASD DESIGN LOAD COMBINATIONS FOR DIRECT USE WITH CORRESPONDING PRESSURE-DESIGNED SYSTEMS ADDITIONAL ENGINEERING IS REQUIRED FOR DESIGN CONDITIONS THAT EXCEED THE CONSIDERATIONS OF THIS MASTER PLAN. CALCULATION NOTES: 1. INTERPOLATION OF THESE RESULTS ARE NOT PERMITTED WITHOUT SIGNED AND SEALED RESULTS. 2. PRESSURES HEREIN ARE VALID FOR CONDITIONS EQUAL OR LESS THAN THE DESIGN CONDITIONS LISTED. FOR CONDITIONS EXCEEDING THOSE LISTED, VISIT ECALC.IO/WIND TO CALCULATE A SITE SPECIFIC PRESSURE 3.
