BONDED POST-TENSIONING SYSTEM MINIMIZES MAINTENANCE FOR GARAGES

As part of a comprehensive improvement plan to upgrade the Baltimore/Washington International Airport's (BWI) functionality, a state-of-the-art parking garage was designed. This garage will consolidate the airport's eight rental car companies into one location. To minimize costs, a VSLAB post-tensioning system from the VSL firm was chosen. The post-tensioning technique counteracts tensile stresses and deflections from externally applied loads and provides "active" reinforcement. As compared with rebar reinforced concrete, this technique boasts greater clear spans for the same member depth, enhanced crack control, larger floor-ceiling heights and reduced maintenance. While post-tensioning design for parking garages can be either an unbonded or a bonded system, bonded systems, which are the industry standard for concrete bridge construction, are becoming more popular for garages. Bonded systems tend to offer greater longevity and flexibility. In addition, bonded systems tend to yield significant lifecycle cost savings. This was the system chosen for BWI. BWI's garage opened in November 2003 and has freed up more than 1,000 prime parking spaces in the terminal parking garage.
