| Abstract |
This paper investigates the interaction of structural steel reinforcement and high performance fiber reinforced cementitious composites (HPFRCCs) in uniaxial tension. The effects of cement composite on the steel reinforced composite deformation behavior are experimentally investigated and contrasted to conventional reinforced concrete. The variables included conventional concrete versus HPFRCCs with different types of fibers, tension member size, and loading type. The substitution of conventional concrete with HPFRCCs, which are defined by an ultimate tensile strength higher than their first cracking strength and the formation of multiple cracking during the deformation process, has shown to provide improved load-deformation characteristics in terms of reinforced composite tensile strength, deformation mode, and energy absorption. The HPFRCC matrix stiffens the specimen at uncracked sections and also strengthens it at cracked sections. Hence, the composite load-deformation response is significantly improved in terms of axial load-carrying capacity as well as ductility. |
