Ductility of Partially Prestressed Concrete Beam

Abstract:

Article Preview

Ductility of partially prestressed concrete beams was numerically analyzed. For a given value of reinforcement index, corresponding curvature ductility factors of an unbonded prestressed concrete beam as well as a bonded prestressed concrete beam are analyzed and compared. It is generally observed that, when reinforcement index is between 0.20 and 0.30, the ductility factor of an unbonded beam is higher than that of bonded one about 10 to 15 percent. While reinforcement index is between 0.15 and 0.20, the ductility factor of an unbonded beam is near that of bonded one. When reinforcement index we is smaller than 0.15, the ductility factor of an unbonded beam is usually lower than that of bonded one about 10 to 15 percent.
