The webinars offered by ASCE are the easiest ones for me to present groups. I appreciate how consistently ASCE organizes its webinars. - Dana M. Hardy, Executive Secretary City of Oklahoma Utilities Administration
INSTRUCTOR: T. Eric Stafford, P.E.
Purpose and Background
The newest edition of ASCE 7 (2016) includes significant technical and organizational changes to the wind loading provisions from the 2010 Edition (ASCE 7-10). This webinar addresses many of those significant changes. The basic wind speed maps have been revised to reflect new wind speed contours for the interior of the United States in addition to a new wind speed map specific to risk category IV buildings and structures. It discusses the impact of the new wind speed maps. The commentary has been revised to provide guidance on how to design buildings for tornadoes. Roof pressure coefficients (GC) have been revised based on new research. These changes, along with many others, are covered in this webinar. Attendees will gain an acute understanding of the important changes to the requirements for determining wind loads in ASCE 7, in addition to a thorough explanation of the rationale for changes to the provisions. The impact of these changes on the design of buildings for wind loads will be clearly demonstrated with illustrations and examples as applicable.
