Insurance claims from Hurricane Isaac losses to insurers could total $1.2 billion.

On August 28th-30th, 2012 Hurricane Isaac made a landfall along the coast of Southeast Louisiana in Plaquemines Parish and west of Port Fourchon. Maximum sustained winds were 80mph at this landfall.  (Source: NOAA)

Today, many property and business owners are still dealing with the aftermath of Hurricane Isaac insurance claims in New Orleans, Metairie, Baton Rouge, Shreveport, Lafayatte and surrounding areas of Louisiana.

Most insurance claims in the United States are grossly underpaid.  In some cases, policyholders may choose to work with a public adjuster.

Wind/Building Interactions

When wind interacts with a building, both positive and negative (i.e., suction) pressures occur simultaneously. (Note: negative pressures are less than ambient pressure, and positive pressures are greater than ambient pressure.) An office building must have sufficient strength to resist the applied loads in order to prevent wind-induced building failure. The magnitude of the pressures is a function of the following primary factors:

When a building is pressurized, the internal pressure pushes up on the roof. This push from below the roof is combined with the suction above the roof, resulting in an increased wind load on the roof. The internal pressure also pushes on the side and rear walls. This outward push is combined with the suction on the exterior side of these walls. Therefore, a pressurized building increases the wind load on the side and rear walls (see Figure 4) as well as on the roof.

Building height. Wind speed increases with height above the ground. Therefore, the taller the office building, the greater the speed and, hence, the greater the wind loads.
