Flow Modeling Proves Hurricane Damage Caused by Wind, Not Water
A steel storage building located on a canal between downtown New Orleans and Lake Pontchartrain was damaged during Hurricane Katrina. The insurance company claimed that the damage, where the walls were pushed outward in two areas, was water-related. As the insurance only covered wind damage, the claim was denied. TRC Companies, Inc., representing the owners of the storage building, faced the challenge of proving that the damage was caused by wind, not water. The traditional approach of applying equations relating force and wind speed would not have included information about the building shape or accounted for the air flowing through open doors inside the building. TRC determined that a more accurate simulation of the pressure forces on the building would provide more persuasive evidence that the damage was wind-related.

Ensuring Building Safety During 'The Big Dig' with ANSYS/Mechanical
The Central Artery/Tunnel Project, also known as 'The Big Dig', was a massive undertaking in Boston, Massachusetts, aimed at replacing the Interstate 90 roadway. The project involved constructing a new seven-mile, 8-10 lane roadway and various interchanges, most of which were to be built 70 feet beneath the city. However, the project posed significant challenges due to its proximity to some of the largest and oldest buildings in downtown Boston. One such building was the One Financial Center, a 46-story office building located just 25 feet away from a 100-feet deep excavation for the tunnel. The building's owners were concerned about the potential effects of the excavation on the building's stability. The excavation process involved a 'de-watering' step, where water was removed from the dig site and surrounding soil. This could cause the ground to compress, potentially leading to building settlement, structural stress, and damage.
