New Rental Car Facility at San Jose Airport Stabilized using DYWIDAG Post-Tensioning Systems

The Norman Y. Mineta San Jose International Airport in the center of the city of San Jose, California, is the only commercial airport in Silicon Valley. The airport is located near San Francisco and registered approx. 10.7 million passengers in 2007. In order to be able to accommodate an expected passenger volume of more than 17 million by 2017, the airport is currently being enlarged. In addition, the access roads are being expanded, and a new parking structure and rental car facility are being built opposite the restructured Terminal B.

In addition to 350 customer parking spaces, the Consolidated Rental Car (CONRAC) Facility offers 3,000 spaces for all rental car companies. The center facilitates passengers’ access to rental cars and helps to alleviate traffic congestion around the airport. The CONRAC Facility was completed at the end of June 2010.

The 8-level structure consists of precast, post-tensioned concrete beams and columns, cast-in-place shear walls, and precast doubletee deck panels. In order for the structure to resist lateral forces during seismic events, Unbonded DYWIDAG Multistrand Tendons were installed into the collector beams across the precast element joints and into the shear walls.

DSI USA supplied approx. 89,000m (292,000lf) of extruded and greased strand with PE sheathing as well as Type 19x0.6" and 27x0.6" MA Anchorages. Additionally, DSI USA also provided the equipment necessary for post-tensioning.

Vehicle access to the CONRAC Facility is provided through two helical ramps. These cast-in-place ramps were post-tensioned using approx. 18,630m (61,122ft) of 0,5" Zero Void Monostrand Tendons.
