Abstract

"Extreme winds impacting civil structures lead to death and destruction in all regions of the world. Specifically, tornadoes and hurricanes impact communities with severe devastation. On average, 1200 tornadoes occur in the United States every year. Tornadoes occur predominantly in the Central and Southeastern United States, accounting for an annual $1 billion in economic losses, 1500 injuries, and 90 deaths. The Joplin, MO Tornado in 2011 killed 161 people, injured more than 1000, destroyed more than 8000 structures, and caused $2.8 billion of property loss. Hurricanes occur predominantly on the United States East coast regions and along the coast of the Gulf of Mexico, accounting for $21.2 billion in economic losses and 159 deaths on average each year ($19.4 billion per event). Data has shown that hurricanes have stricken coastal cities more frequently and more intensely. In 2020, 30 named storms formed in the Atlantic Ocean and 13 of them have progressed into hurricanes. The goal of this research is to investigate the true loadings of extreme winds on civil structures in order to design safer buildings and communities. To accomplish this goal, research has been conducted to properly model these winds using physical and numerical simulation (chiefly computational fluid dynamics simulation), investigate the wind characteristics of extreme winds, and determine how these winds impact civil structures (wind effects), which is required to conduct a hazard-resistant design"--Abstract, page iv.
