The major editorial change is a … The major editorial change is a complete reorganization to a multiple-chapter format as done previously for seismic loads with the objective being to make the provisions easier to follow. A separate wind speed map will be included for Occupancy Category IV buildings, where previously Category III and IV buildings were addressed on a combined map. ASCE 7-10 wind maps and associated wind speeds will be updated in 7-16. They reduced the wind in the "strength design" and ASD Load Combinations by 1.6. The wind speeds for the county-specific maps may vary somewhat. DISCLAIMER. Wind Velocity in ASCE 7 -10 3/09/201 6 ASCE 7-10, “Minimum Design Loads for Buildings and Other Structures”, introduces significant changes to wind load design. In general, the greater the importance of a building, the higher the Importance Factor or … The wind-load factor is then applied to determine the design wind pressure. ASCE 7-10 uses three different basic wind speed maps for different categories of building occupancies. Basic wind speed: (for strength design) ASCE 7-10 removes important factor Iw from wind load equation from ASCE 7-05 and replaces it with three different wind maps. Florida. Reorganization of wind provisions – Chapter 6 of ASCE 7-5 – Chapters 26 through 31 of ASCE 7-10 – Crosswalk table of sections ; Basic wind speed maps – Strength design-level wind speeds – Risk categories and classification of buildings – Load combinations – Comparison of design pressures ; Wind-borne debris regions – Applicability ASCE 7-10 includes wind speed maps for locations throughout the country. Easy-to-use mapping features offer a better way to look up key design parameters specified by Standard ASCE 7. FBC 17 handles the case of ASD design a little different, it modifies the wind speed used in the calculations to an ASD velocity using Equation 16-33. Basic wind speed in U.S. is shown in wind hazard map: Figure 26.5-1A. NCSEA Webinar –ASCE 7-10 Changes in Wind Load Provisions 26 Why Change the Map? A straight translation of the 110 and 120 mph wind speeds from ASCE 7-05 to the 700 year return period maps in ASCE 7-10 would yield triggers of 140 mph and 150 mph respectively. NEW ASCE 7 Hazard Tool identifies hurricane-prone regions and wind-borne debris regions, as defined in ASCE 7-16, Chapter 26 and ASCE 7-10.. Serviceability wind speeds now returned with site wind … 7th Edition (2020) FBCB (ASCE 7-16 Figure 26.5-1D) While the wind speed maps in ASCE 7-16 have been revised significantly for the nonhurricane-prone region, for the State of Florida, the only significant change to the wind speed maps is the introduction of a new wind speed map for Risk Category IV buildings and structures. The wind speeds used with ASCE 7-10 equations need to be based on the new maps. Then increase the minimum and some of the Tables values by the 1.6 factor. Purpose and Background. Furthermore, separate wind maps for Risk Categories III and IV needed to be developed for ASCE 7-16 using a structural reliability-based procedure described That coordination certainly needs to take place between purchaser and manufacturer. This helpful guide focuses on the wind load provisions of Minimum Design Loads for Buildings and Other Structures, Standard ASCE/SEI 7-10, that affect the planning, design, and construction of buildings for residential and commercial purposes.The 2010 revision of the Standard significantly reorganized the wind load provisions, expanding them from one to six chapters.

ASCE 7-10 code has a reduction factor of 0.6 on wind loads and 0.7 on seismic loads. ASCE reports that wind speeds will be reduced for much of the U.S. where located outside of hurricane-prone regions. MecaWind includes ASCE 7-05, ASCE 7-10 and ASCE 7-16, and includes all of the changes in the new standard. The wind load is almost the same between the 7-05 and the 7-10 ASCE. Wind Borne Debris Regions Per ASCE 7-10, section 26.2, Wind Borne Debris regions are Areas within hurricane-prone regions where impact protection is required for glazed openings (buildings in Risk Category I are exempt – ASCE 26.10.3 & IBC 1609.1.2) Protection of glazed openings is required (ASCE 7 … Shaded (Special Wind Region) areas, mountainous terrain, gorges, and ocean promontories should be examined for unusual wind conditions. ASCE 7-10 "Minimum Design Loads for Buildings and Other Structures" contains several changes regarding wind loads. Allowable Stress Design Wind Speed: In ASCE 7-10, we use ultimate wind loads and then the load combinations factors are applied if Allowable Stress Design (ASD) is being performed. To assist the process, this report has produced appropriate maps. C1.3.1.3 of ASCE 7-10 to Section 1.3.1.3 of ASCE 7-16. For this edition (05), the ASD wind-load factor is 1.0 and the strength design wind-load factor is 1.6. ASCE 7-10 and 7-16 incorporates Risk Category (i.e., importance factor) into the wind speed maps, and that is why there are 3 maps in ASCE 7-10, and 4 maps in ASCE 7-16. The American Society of Civil Engineers (ASCE) Structural Engineering Institute (SEI) publishes Minimum Design Loads for Buildings and Other Structures (ASCE/SEI 7-10), which describes wind load design methods and is the basis for most building codes in the United States. to calculate design pressures, introducing potential confusion. ASCE 7-10 provides two methods for wind load calculation: a simplified procedure and an analytical procedure. I appreciate how consistently ASCE organizes its webinars. The major editorial change is a complete reorganization to a multiple-chapter format as done previously for seismic loads with … Note that when the wind speed maps were being developed for ASCE 7-98, the wind load factor at the time was equal to 1.53, which the wind load task committee rounded down to 1.5 and computed an ultimate load return period of 475 years, which subsequently rounded up to 500 years. ASCE 7-10 Minimum Design Loads for Buildings and Other Structures contains several changes regarding wind loads. The jump in thinking is IMHO money. With ASCE 7-10 each geographic location no longer had a single Basic Wind Speed, but multiple Basic Wind Speeds conveyed in multiple maps depending on Risk Category. 9/7/2017 9 ASCE 7‐16 –Wind Provisions MRI Design Wind Speed Maps ... •Evaluation of ASCE 7‐10, Flat Roof C&C • … ASCE 7-10 "Minimum Design Loads for Buildings and Other Structures" contains several changes regarding wind loads.
