Enhanced Residential Building Code for Tornado Safety
The EF5 tornado that occurred in Moore, Oklahoma on May 20, 2013, provided a rare opportunity to study the effects of multiple major tornadoes on a single community in a relatively short timeframe. Data collected immediately after the tornado indicate an ordered progressive collapse mechanism for residential wood-frame structures with slightly different progressions for low-pitch and high-pitch roofs. This failure progression indicates that a continuous load path from the roof to the foundation is the most important aspect of design and construction for tornado resistance of residential structures. Performance of homes in a neighborhood constructed using more-robust methods indicates that the damage path caused by an major tornado can be narrowed by improving the overall structural system with a series of relatively simple items. Twelve code modifications proposed by the authors to create a more-robust structural system intended to withstand winds up to (135 mph), or an EF2 rating, are presented in this paper. The city of Moore adopted these code changes on March 17, 2014.
