Title:

Structural Behavior of Ultra High Performance Concrete Beams Without Stirrups

Accession Number:

Abstract:

This paper presents comparative behavior of Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) beams under flexural and shear loading. Four large scale UHPFRC beams with different reinforcement ratios were tested under dominant shear and flexure loading. The beams were not provided with any shear reinforcement in order to take advantage of high tensile strength offered by UHPFRC. Two of the beams were tested under dominant shear loading and remaining two beams were tested under dominant flexural loading. Comparative results indicate that UHPFRC beams, without stirrups, subjected to shear loading did not experience any reduction in either ductility or moment capacity. This enhancement in performance can be attributed to improved tensile cracking resistance, and enhanced shear strength due to bridging effect of fibers in Ultra-High Performance Concrete (UHPC).
