Evaluation and Structural Behavior of Deteriorated Precast ...

Adjacent precast, prestressed box beam bridges have a history of poor performance and have been observed to exhibit common types of deterioration including longitudinal cracking, concrete spalling, and deterioration of the concrete top flange. The nature of these types of deterioration leads to uncertainty of the extent and effect of deterioration on structural behavior. Due to limitations in ...

Structurally Composite, Thermally Efficient Precast Concrete

Composite precast concrete panels are fab-ricated in a long-line precast concrete pro-duction facility. In some cases, panels are prestressed, but can also be designed using only conventional mild steel reinforcement. Panels are produced flat with the outer fin-ished surface facing down in the form.

What is Precast, Prestressed Concrete? - Tindall Corporation

Both structural and architectural precast concrete may be prestressed or nonprestressed. Prestressed concrete may be achieved using either pretensioning or post-tensioning methods. With pretensioning methods, the strands are tensioned before placing the concrete and after the concrete has gained adequate strength, the tension is released with ...
