Webinar Series Schedule
Wednesday, June 16, 2021
12:00 p.m. ~ Summary of Local Effects of Global Mean Sea Level Increases and Changes Expected to Wind in Connecticut
James O’Donnell, Ph.D., Executive Director of the Connecticut Institute for Resilience & Climate Adaptation (CIRCA) at the University of Connecticut
This presentation will include:
1:00 p.m. ~ Lateral Load Design using the IBC and ASCE 7 and Recent Lessons Learned from Disasters
Edwin T. Huston, P.E., S.E., Principal with the structural engineering firm of Smith & Huston Inc., in Seattle, WA
This presentation will discuss how winds and storms damage structures, highlighting patterns of damage. We will explore direct damage from in-line wind forces, cyclonic wind forces, windborne debris damage, and storm surge damage. The presentation will also briefly discuss structural response to wind, code response to damage, and load path issues. We will finish with a discussion of the role that load path plays in forensic investigations.
Friday, June 18, 2021
12:00 p.m. ~ Latest Updates to the ASCE 7-16 Wind Provisions and a preview of the ASCE 7-22 provisions
Donald R. Scott, S.E., a Senior Principal with PCS Structural Solutions, and Cherylyn Henry, P.E., the structures group lead and a project manager with ZAPATA
As many of the Northeastern States begin to adopt the 2018 IBC, the referenced standard will be ASCE/SEI 7-16: Minimum Design Loads and Associated Criteria for Buildings and Other Structures. This presentation will review the major revisions to the standard that affect the practicing engineer in their daily practice. Also nearing completion are the revisions to the ASCE 7-16 standard that will be published as ASCE/SEI 7-22. Mr. Scott and Ms. Henry will review a few of the major revisions to the standard for the 2022 edition that might benefit current projects.
1:00 p.m. ~ Wind Design and Damping Strategies for Bridges and Tall Buildings
Un Yong Jeong, Ph.D., P.Eng, a Principal at Gradient Wind, Ontario, Canada
This presentation will cover:
Wednesday, June 23, 2021
8:00 a.m. ~ Recent Advances in Machine Learning and its Applications in Wind Engineering
Sungmoon Jung, Ph.D., Professor of Civil & Environmental Engineering at the Florida A&M University-Florida State University College of Engineering College of Engineering
The speaker will first introduce the basics of machine learning and its recent development. In particular, more time will be spent to explain the Convolutional Neural Network (CNN), which shows excellent performance in image recognition. The speaker will then present three different applications of machine learning in wind engineering. The first is estimation of tree failure consequences using areal images. The second is to classify the satellite image for wind engineering problems. The third is estimation of flutter coefficients using bridge deck geometry. The presentation will be concluded with the discussion of future opportunities.
1:00 p.m. ~ Overview of the Proposed Tornado Loads for ASCE 7-22, including Northeast US-Specific Requirements
Marc Levitan, Ph.D., Lead Research Engineer for the National Windstorm Impact Reduction Program at the National Institute of Standards and Technology
This presentation will provide an overview of the tornado load provisions proposed for incorporation into ASCE 7-22 and their development. These provisions are based on the ASCE 7 framework for determination of loads from other types of windstorms, with many modifications for tornadoes. Design speeds are defined using the first-ever engineering-derived probabilistic tornado wind speed maps, which also account for the dependency of tornado risk on the plan size of the building or structure. Unique tornado characteristic such as the bullnose-shaped vertical velocity profile, strong updrafts, and atmospheric pressure change are also accounted for. These tornado load proposals are currently working their way through the standards approval process for inclusion in ASCE 7-22. Highlights of a case study comparing tornado loads and wind loads will also be presented, including a look at impacts of tornado load provisions in the Northeast U.S.
