Parking Structure C
John Wayne Airport's new Parking Structure C is a five-level, post-tensioned concrete structure comprising a total area of approximately 725,000 square feet. Parking Structure C will provide about 2,000 parking spaces to replace the 1,241 spaces that were eliminated by the deconstruction of Parking Structure B1. Completed in late 2010, Parking Structure C will open concurrent with Terminal C in late 2011.
This new structure is the first concrete structure built in the United States utilizing state-of-the-art engineering technology known as Buckling Restrained Bracing or "BRB," a method designed to maximize both safety and efficiency. This approach includes construction of a special frame consisting of slender structural members, each made up of a steel core encased within a steel outer casing filled with concrete.
Developed in the 1980s, BRB technology uses the flexibility of steel more effectively than traditional bracing systems. A main purpose of BRB is to laterally brace, or support, critical sections of a multi-level structure where "bending" of the structure may occur during an earthquake. In the case of JWA's Parking Structure C, the BRB system will not only ensure maximum seismic stability, but also safety and efficiency of the structures.
