Concrete Creep Analysis Method Based on a Long-Term …

Concrete creep plays a significant role in the long-term performance of the prestressed concrete structure. However, most of the existing prediction models cannot accurately reflect the in-site concrete creep in a bridge construction environment. To improve the prediction accuracy of creep effects in concrete structures, an innovative creep analysis method is developed in this study

Prestressed Concrete - Post Tensioning System

Prestressed concrete structure deflects more than conventional reinforced concrete, thus giving ample warning before collapse. And this is an improved safety factor. Slab On Grade (unbounded) is also increasingly popular with industrial structures where joints are the major weakness in these concrete structures.
