Abstract: Design methods for the shear resistance of reinforced and prestressed concrete beams are based on empirical evidence. Due to different approaches in their development, different equations are used to calculate the shear ...

Abstract: An experimental program was conducted to investigate the stress relaxation properties of large-diameter bars [65 to 70 mm (2.5 to 2.75 in.) nominal] for posttensioning applications. This study was a component of ...
