Performance of precast, prestressed concrete I-girders employing 0.7-in. diameter prestressing strands under shear-critical loading conditions
The majority of precast, pretensioned concrete elements are currently fabricated using 0.5- or 0.6-in. diameter prestressing strands. However, in recent years, potential benefits such as reduced fabrication costs and ...
Development of end-region cracks in pretensioned concrete I-girders employing 0.7-in. diameter strands
Although 0.5- and 0.6-in. diameter strands are commonly used in the prestressing industry, there is a growing interest in the implementation of 0.7-in. diameter strands. However, the greater prestressing force induced poses ...
