Owner: JC Penney Corporation
System: Carbon Fiber Composite Strengthening System
Quantity: 516 Inverted “T” Beams
Area: 62,000 SF Carbon Fiber Wrap
Completed: October, 2001
At JC Penney’s Corporate Headquarters located in Plano, Texas, problems were discovered in many of the precast beams that support the floor structure of the North and South Parking Garages. Phase 3 of the repair work, designed by Wiss, Janney, Elstner Associates, included the application of a twolayer, carbon-fiber wrap system to the bottom surface of the precast, pre-stressed inverted “T” beams.
Strict limits were placed on the contractor regarding the number of parking spaces that could be blocked at any one time, in order to keep the majority of both garages in service. Beams that supported drive aisles had to be repaired on Friday evenings in order to obtain 48 hours of cure time prior to re-opening on Monday morning.
An acrylic topcoat was applied to the black carbon-fiber fabric making the repaired beams barely noticeable.
