| | FBC = FLORIDA BUILDING CODE 2010 |
| | FBC*= FLORIDA BUILD'G CODE (CITY AMEND) |
| | F.S.= FLORIDA (STATE) STATUTE |
| | |
| | 1) FBC 1609.3 - BASIC WIND SPEED |
| | BY REFERENCE FROM THE 2010 FBC, THE CURRENT DESIGN |
| | STANDARD IS ASCE 7-10, WHICH IS BASED ON ULTIMATE |
| | DESIGN WIND SPEED, NOT ALLOWABE STRESS DESIGN WIND |
| | SPEED. |
| | THE SOLAR PHOTO VOLTAIC SYSTEM IS AN APPURTENANCE TO |
| | THE BUILDING. AS SUCH IT MAY BE CONSIDERED AS THE |
| | LOWEST RISK CATEGORY ALLOWED BY FBC 1609.3, WHICH IS |
| | RISK CATEGORY I. THE DESIGN WIND SPEED SHALL BE |
| | OBTAINED FROM FBC FIGURE 1609C, AND THAT GIVES AN |
| | UTLIMATE DESIGN WIND SPEED OF 155 MPH FOR THIS |
| | LOCATION. PLEASE REVISE THE STRUCTURAL CALCULATIONS TO |
| | REFERENCE THE CURRENT DESIGN STANDARD FOR WIND LOADING, |
| | AND STATE THE CORRECT DESIGN WIND SPEED. THE ULTIMATE |
| | DESIGN WIND SPEED MAP FOR RISK CATEGORY I BUILDINGS AND |
| | STRUCTURES IN PALM BEACH COUNTY CAN BE VIEWED AT WWW.CI |
| | TYOFWPB.COM/CONSTRUCTION/PDF/FIGURE%20C%20DATA%20PAGES% |
| | 202_PALMBEACH.PDF |
| | |
| | 2) FBC 1609.1.1 - WIND SPEED |
| | STRUCTURAL CALCULATION PAGE 1 OF 8 REFERENCES ASCE |
| | 7-05, AND STATES THAT THE DESIGN WIND SPEED (FOR |
| | ALLOWABLE STRESS DESIGN) IS 120 MPH. AS STATED IN |
| | COMMENT 1 ABOVE, THE CURRENT DESIGN STANDARD IS ASCE |
| | 7-10, WHICH IS BASED ON ULTIMATE DESIGN WIND SPEED, NOT |
| | ALLOWABE STRESS DESIGN WIND SPEED. |
| | FROM FBC FIGURE 1609C, THE UTLIMATE DESIGN WIND SPEED |
| | IS 155 MPH AT THIS LOCATION. PLEASE REVISE THE |
| | STRUCTURAL CALCULATIONS TO REFERENCE THE CURRENT DESIGN |
| | STANDARD FOR WIND LOADING, AND SHOW WHAT EFFECT, IF |
| | ANY, THAT HAS ON THE UPLIFT AND SLIDING FORCES, AND THE |
| | ANCHOR TYPE, SIZE AND SPACING. |
| | |
| | 3) FBC 1604.2 - TRANSFER OF LOAD |
| | THE FOLLOWING WILL BE A PROVISO ONCE THE OTHER PLAN |
| | REVIEW COMMENTS ARE ADDRESSED, AND A PERMIT IS BEING |
| | ISSUED: |
| | FOR THE ANCHOR CALCULATIONS, STRUCTURAL CALCULATION |
| | PAGE 2 OF 8 REFERENCES ACI 318 APPENDIX D FOR CRACKED |
| | CONCRETE, AND DRAWING SHEET PV-4, NOTES 1 THROUGH 3, |
| | STATE THAT THE ROOF DECK IS ASSUMED TO BE STRUCTURAL |
| | CONCRETE AND REQUIRE THE CONTRACTOR TO NOTIFY THE |
| | DESIGNER IF THE FIELD CONDITIONS DO NOT MATCH THE |
| | DRAWINGS. IT IS NOTED THAT THE DESIGN IS BASED UPON THE |
| | ASSUMPTION OF A STRUCTURAL CONCRETE DECK CAPABLE OF |
| | TRANSFERRING THE LOADS TO THE PRIMARY STRUCTURAL |
| | ELEMENTS, AND THAT THE CONTRACTOR IS REQUIRED NOTIFY |
| | THE DESIGNER IF THAT ASSUMPTION IS NOT FOUND TO BE |
| | CORRECT IN THE FIELD. |
