Assessment and Restoration of Post-Tensioned Buildings – Parking Ramp Structures
The use of un-bonded post-tensioned (PT) reinforcement in concrete structures has been popular for many decades in parking ramp structures. The use of PT reinforcement in parking ramp structures greatly reduces the amount of cracking and possible leakage in the structure and also allows economical long-span construction. The boom of parking structures in the United States began in the 1960s which coincides with the start of heavy use of deicing products. Many of these early PT structures have been found to be in a deteriorated condition with varying degrees of damage to the PT systems. This paper presents a detailed explanation of the deterioration mechanisms that affect post-tensioned ramp structures addressing the most common types of PT systems: button head and sheathing strand systems including current testing techniques utilized in the in their evaluation. Detailed case studies are presented to illustrate the detrimental effects of deterioration mechanisms on post-tensioned structures providing specific repair recommendations in order to mitigate and prevent structural related problems for un-bonded post-tensioned parking ramp structures.
