ABS Consulting Releases Chase Tower Section of Hurricane Ike Study
December 15, 2008
ABS Consulting recently released the Wind Effects of Hurricane Ike on Chase Tower in Downtown Houston (PDF) portion of its Hurricane Ike study. A full report is scheduled to be released the first quarter of 2009, which will include the following sections:
- Purpose and Background
The objective of this study is to survey and evaluate damage resulting from Hurricane Ike to improve loss estimation methods. The geographic scope of the study includes affected areas within and around Houston and coastal areas from Freeport to Port Sabine. Commercial and industrial facilities as well as infrastructure are the primary, though not exclusive, focus of this study.
- Extreme Wind Environment
This section presents predicted and observed wind fields and discusses unique or significant characteristics. Observed data are obtained through NOAA and field deployments by major universities. Predicted wind fields produced by EQECAT models are compared with observed data.
- Storm Surge and Flooding
This section presents predicted and observed storm surge elevations and discusses unique or significant characteristics. Observed data are obtained through NOAA tidal gage stations. Predicted elevations produced by EQECAT models are compared to observed data. Riverine and surface flooding due to extreme rainfall are also discussed.
- Performance of Buildings and Other Structures
This section presents observed damage due to extreme wind, storm surge, and flooding. The mechanics of fluid/structure interaction are discussed in general with correlations of damage with wind speed and surge elevation. Special case studies are discussed in detail.
- Infrastructure and Business Interruption
This section discusses infrastructure damage and business interruption resulting from Hurricane Ike. Disruption of electric power and other lifelines are discussed including the impact of Ike on parts of the US beyond the landfall region.
- Historical Hurricanes
This section discusses previous hurricane events affecting Houston and the upper Gulf of Mexico. Specific topics include industrial and commercial facilities, competition for recovery resources, property losses, and human casualties.
