DEFYING THE WINDS: STRUCTURAL DESIGNFOR TORNADO LOADS ON BUILDINGS
Speaker: Dr. Marc L. Levitan, PhD National Institute of Standards and Technology
Until now, tornado hazards have not been considered in the design of conventional buildings, despite the fact that tornadoes and tornadic stormscause more fatalities and insured losses than hurricanes and tropicalstorms. This gap is addressed for the first time in ASCE 722, which includesrequirements for tornado loads. Join Dr. Marc Levitan for an overview of thenew tornado provisions in ASCE 7 22, along with background on the needfor such requirements and their development. Marc will provide a basicunderstanding of tornado hazards, the ASCE 722 tornado load methodology,significant differences between procedures for determination of wind loadsand tornado loads, and changes to load combinations including tornadoes.
