The costliest natural disaster in U.S. history was Hurricane Katrina, which made landfall on August 29, 2005 at 7:10 a.m. EDT (6:10 CDT, local time) in Plaquemines Parrish, La. Tragically, Katrina caused widespread damage and loss of life but also provided an opportunity to collect data on wood-frame construction which will be useful for design engineers and building code officials in order to design safer and stronger buildings in the future. The objective of this study was to gather and process perishable wind damage data on residential wood-frame structures in nonflooded regions of Mississippi that can be used by the research and design code development community to improve the performance of wood-frame structures to strong wind loading. This study consisted of 3 days of data acquisition of wind damage to wood-frame structures along the U.S. Gulf Coast and was funded by the National Science Foundation. A total of 27 case studies, ranging from entire subdivisions to individual wood-frame structures, were examined in detail. This paper presents both general and specific observations during data reconnaissance. It was generally found that most residential wood-frame construction in the regions inspected are built using conventional construction practices, when engineered or prescriptive construction should be used. The paper is divided into (1) structural; (2) nonstructural; and (3) general observations.
