ASCE/SEI 7-22 Risk Category IV Basic Wind Speed Map for Hillsborough County- 2023
This dataset contains NIST-WindMaps: ASCE/SEI 7-22 Risk Category IV Basic Wind Speed Map - (3000yr) for the State of Florida.Florida Building Code (FBC) 8th Edition (2023) FIGURE 1609.3(3)ULTIMATE DESIGN WIND SPEEDS, VULT, FOR RISK CATEGORY IV BUILDINGS AND OTHER STRUCTURES. Risk Category IV - Nature of Occupancy: Buildings and other structures designated as essential facilities, including but not limited to: Group I-2 occupancies having surgery or emergency treatment facilities. Fire, rescue, ambulance and police stations and emergency vehicle garages. Designated earthquake, hurricane or other emergency shelters. Designated emergency preparedness, communications and operations centers and other facilities required for emergency response. Power-generating stations and other public utility facilities required as emergency backup facilities for Risk Category IV structures. Buildings and other structures containing quantities of highly toxic materials that: Exceed maximum allowable quantities per control area as given in Table 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. Aviation control towers, air traffic control centers and emergency aircraft hangars. Buildings and other structures having critical national defense functions. Water storage facilities and pump structures required to maintain water pressure for fire suppression.
<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 15% probability of exceedance in 50 years (Annual Exceedance Probability = 0.00333, MRI = 300 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>
