Shear strength and behavior of ultra high performance reinforced concrete deep beams with stirrups

Abstract EN

Ultra-high performance fiber reinforced concrete (UHPC) is a new class of concrete that has been developed in recent decades, it has enhanced properties such as ; very high compressive strength, improved tensile strength, durability and due to presence of steel fibers the concrete shows more ductility than conventional types of concrete.

The ultimate shear strength being obtained by Neural Network for ultra high performance concrete (UHPC) deep beams.

Parameters considered from Neural Network model were different type and amount of shear reinforcement (vertical and horizontal), pvfy from 1.27 to 7.46MPa, phfy from 2.38 to 5.30MPa and concrete compressive strength, f`c from 25 to 125 MPa.

Based on the 321 data from literature, the ultimate shear strength was modeled by Neural Network for all the specimens to be used for (UHPC) beams and all the results compared with those obtained by ACI Code and proposed equation by Aziz.
