ASCE/SEI 7-22 Risk Category III Basic Wind Speed Map for Hillsborough County- 2023
This dataset contains NIST-WindMaps: ASCE/SEI 7-22 Risk Category III Basic Wind Speed Map - (1700yr) for the State of Florida.Florida Building Code (FBC) 8th Edition (2023) FIGURE 1609.3(2)ULTIMATE DESIGN WIND SPEEDS, VULT, FOR RISK CATEGORY III BUILDINGS AND OTHER STRUCTURES. Risk Category III - Nature of Occupancy: Buildings and other structures that represent a substantial hazard to human life in the event of failure, including but not limited to: Buildings and other structures whose primary occupancy is public assembly with an occupant load greater than 300. Buildings and other structures containing Group E occupancies with an occupant load greater than 250. Buildings and other structures containing educational occupancies for students above the 12th grade with an occupant load greater than 500. Group I-2 occupancies with an occupant load of 50 or more resident care recipients but not having surgery or emergency treatment facilities. Group I-3 occupancies. Any other occupancy with an occupant load greater than 5,000. Power-generating stations, water treatment facilities for potable water, wastewater treatment facilities and other public utility facilities not included in Risk Category IV. Buildings and other structures not included in Risk Category IV containing quantities of toxic or explosive materials that: Exceed maximum allowable quantities per control area as given in Table 307.1(1) or 307.1(2) or per outdoor control area in accordance with the Florida Fire Prevention Code; and Are sufficient to pose a threat to the public if released.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>In this project, the University of Florida (UF) GeoPlan Center is providing Geographic Information System (GIS) technical assistance for creating updated Florida statewide Ultimate Design Wind Speed line maps for the 8th Edition (2023) update to the Florida Building Code (FBC). Updates to Figures: 1609.3(1), 1609.3(2), 1609.3(3) and 1609.3(4) will be based on the standards set forth in Chapter 26 of the American Society of Civil Engineers (ASCE), the Minimum Design Loads and Associated Criteria for Buildings and Other Structures (ASCE/SEI 7-22). In addition, the GeoPlan Center shall provide GIS technical assistance in preparing local wind speed line maps for each building code jurisdiction that is impacted and dissected by the wind speed contours as updated and depicted in the draft Florida Building Code, 8th Edition (2023) Figures 1609.3(1-4) Risk Categories I - IV Buildings and Structures. This final report addresses details of the project’s progress to date on each task listed in the scope of work. In summary, Task 1 is complete, and Task 2 is complete.</SPAN></P><P><SPAN>Notes:</SPAN></P><P><SPAN>1.Values are nominal design 3-second gust wind speeds in miles per hour (m/s) at 33 ft (10m) above ground for Exposure C Category.</SPAN></P><P><SPAN>2.Linear interpolation between contours. Point values are provided to aid with interpolation.</SPAN></P><P><SPAN>3.Islands, coastal areas, and land boundaries outside the last contour shall use the last wind speed contour.</SPAN></P><P><SPAN>4.Mountainous terrain, gorges, ocean promontories, and special wind regions shall be examined for unusual wind conditions.</SPAN></P><P><SPAN>5.Wind speeds correspond to approximately a 1.6% probability of exceedance in 50 years (Annual Exceedance Probability = 0.00033, MRI = 3000 Years).</SPAN></P><P><SPAN>6.Location-specific basic wind speeds shall be permitted to be determined using www.atcouncil.org/windspeed.</SPAN></P><P><SPAN>Ultimate Design Wind Speeds, Vult, For Risk Categories I-IV Buildings and Other Structures</SPAN></P><P><SPAN>https://ufl.maps.arcgis.com/apps/mapviewer/index.html?webmap=3a5d5dd7d44744eeb9537b76534a72a9</SPAN></P></DIV></DIV></DIV>
