One of 25 reports in the series: Research report (Austin, Tex.) available on this site.

Description

In traditional prestressed concrete beams, longitudinal prestressed tendons serve to resist bending moment and transverse mild steel bars (or stirrups) are used to carry shear forces. However, traditional prestressed concrete I-beams exhibit early-age cracking and brittle shear failure at the end zones despite the use of a high percentage of stirrups (4.2%). Moreover, producing and placing stirrups require costly labor and time. To overcome these difficulties, it is proposed to replace the stirrups in prestressed concrete beams with steel fibers.
