Wind Loads - Guide to the Wind Load Provisions of ASCE 7-10 Mehta , Kishor C. , Coulbourne , William L. 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. M.ASCE2 ABSTRACT It is well known that the major change for wind design in ASCE 7-10 Minimum Design Loads for Buildings and Other Structures is the introduction of new wind speed maps that are referred to as ultimate wind speed maps in the 2012 International Building Code (IBC). - Dana M. Hardy, Executive Secretary City of Oklahoma Utilities Administration. The final wind speed map used in ASCE 7-98 was ASCE 7-10 wind maps and associated wind speeds will be updated in 7-16. The wind load is almost the same between the 7-05 and the 7-10 ASCE. I appreciate how consistently ASCE organizes its webinars. You can click on the map below to determine the basic wind speed for that location. 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 DISCLAIMER. 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. Wind Speed Maps - ASCE 7-16 « on: March 09, 2018, 11:12:56 am » I don't know about the rest of you but when I look at the new wind speed maps in the ASCE 7-16, in particular the eastern United States I find the contour lines a bit confusing. You only need to fill in either the city and state or the zip code. The major editorial change is a complete reorganization to a multiple-chapter format as done previously for seismic loads with … In ASCE 7-10 and ASCE 7-16, the wind speed maps and target reliabilities have been updated to incorporate the new analysis of non-hurricane wind data and … Use our ASCE Wind Speeds map to easily obtain the ASCE wind speeds (7-16, 7-10, 7-05) for any location in the contiguous United States, Puerto Rico and Alaska. Alaska maps ASCE 7‐16 –Wind Provisions. Shaded (Special Wind Region) areas, mountainous terrain, gorges, and ocean promontories should be examined for unusual wind conditions. C1.3.1.3 of ASCE 7-10 to Section 1.3.1.3 of ASCE 7-16. 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 … This would have eliminated the WBDR along most the Texas coast and substantially reduce the region in other areas that are considered to be in a WBDR in ASCE 7-05. 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. While the information presented on this website is believed to be correct, SEAOC /OSHPD and its sponsors and contributors assume no responsibility or liability for its accuracy. 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 Based on this when we perform analysis in PVElite using ASCE 7-10, foundation loads which we get in output summary are not 100% wind and seismic. The simplified procedure is for building with a simple diaphragm, roof slope less than 10 degrees, mean roof height less than 30 feet (9 meters), regular shape rigid building, no expansion joints, flat terrain and not subjected to special wind condition. 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 … ASCE 7-10 "Minimum Design Loads for Buildings and Other Structures" contains several changes regarding wind loads. Purpose and Background. Wind speeds for Risk ASCE 7-10 uses wind maps with recurrence intervals of 700, 1700, and 300 years (for Risk Categories II, III-IV, and I respectively) within the standard, and maps of 10, 25, 50, and 100 years recurrence in Commentary Appendix C (Serviceability Considerations). 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. MecaWind includes ASCE 7-05, ASCE 7-10 and ASCE 7-16, and includes all of the changes in the new standard. - Basic wind speeds for Occupancy Category II building and other structures 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. The jump in thinking is IMHO money. Easy-to-use mapping features offer a better way to look up key design parameters specified by Standard ASCE 7.
