Building Damage Analysis following Hurricane Ike on the Bolivar Peninsula, TX
Publication: Coastal Structures and Solutions to Coastal Disasters 2015: Resilient Coastal Communities
ABSTRACT
In 2008, Hurricane Ike made landfall over the Bolivar Peninsula in Texas. Most buildings were single-family residences, elevated on piling foundations. Several thousand houses were destroyed. This paper examines the importance of the elevation of building foundation components relative to the maximum wave elevations on the survival or failure of the building. Storm surge/wave gage measurements are compared to Federal Emergency Management Agency (FEMA) flood insurance rate maps and several Ike-specific storm-surge models. The best accurately predicted the observations near the Gulf. All of the models significantly over-estimated wave conditions on the landward side of the peninsula. Near the Gulf, elevated building failures were initiated when maximum wave-crest elevations reached the bottom of the floor joists, with near 100% failures 1.2 m (4 ft) higher. Farther from the Gulf, failures occurred over a lower, wider range. Most building failures occurred within 678 m (2225 ft) of the Gulf, although more inland buildings were deeply flooded without apparent wave damage.
