McDonald-Mehta Lecture Series 2015: Dr. John W. van de Lindt, Colorado State University
As part of the ongoing 2015 McDonald-Mehta Lecture Series, Dr. John van de Lindt (Colorado State University) traveled to Lubbock to give a lecture called "Wood Building Design for Performance and Resilience to Natural Hazards."
Many thanks to all who were involved.
Design codes represent a minimum lawful requirement for the design of a component, subassembly, or building. Past building codes explicitly target life safety (survival) of building occupants, but over the last two decades performance-based engineering has enabled a new type of (performance) design. The focus for PBE has been on extreme loading which usually occurs as a result of natural hazards loading such as earthquakes, hurricanes, floods, tornadoes, and relevant combinations of these natural hazards. Most recently, it has been recognized that performance of buildings during extreme loading provides only one piece to the recovery puzzle (resilience). This presentation will summarize the evolution of design for wood buildings by starting with low-rise buildings focusing on life safety, moving to performance-based design of mid-rise buildings, and culminating with the design concept of high-rise wood buildings for resilience. An array of natural hazards will be considered including past research on earthquake, flood, and wind loading. Model validation includes test results from two of the world's largest shake table tests conducted in 2009 and 2013 by the presenter.
