Seismic Design of Large Wood Panelized Roof Diaphragms in Heavy Wall Buildings
This presentation will focus on the engineered seismic design of large wood panelized roof diaphragms in tilt-up concrete and masonry wall buildings, with focus on design requirements for strength, stiffness, and proper development and resistance of wall anchorage forces. A historical perspective of how past seismic experience with this building type has influenced today's building code provides a good perspective for the participant to apply the current provisions of ASCE 7-10, 2015 NDS and 2015 SDPWS. Various design illustrations and examples of high load wood structural panel diaphragms, wall anchorage, subdiaphragms, continuity cross ties, chords and collectors will be shown.
Registration will close at 11:59 p.m. on Wednesday, June 14.
John Lawson, S.E., is a licensed Structural Engineer in California and Arizona and has overseen the design of over 100 million square feet of low-slope roof systems. He has a Masters degree in Structural Engineer from Stanford University, and a Bachelors in Architectural Engineering from Cal Poly San Luis Obispo, where he is currently an associate professor. Mr. Lawson is also a Structural Specialist in FEMA’s Urban Search & Rescue program, with special training in collapsed structures, and has been deployed to earthquakes, hurricanes, and the Oklahoma City Bombing.
