- Abstract
The tensile behavior of fiber-reinforced concrete (FRC) members co-reinforced with conventional deformed reinforcing bar (R/FRC members) is analytically investigated in regards to tensile stresses developed in the reinforcing bars, tensile stresses induced in the steel fibers bridging a crack, and the bond mechanism between the reinforcing bar and the concrete matrix. A tension-stiffening model for R/FRC members is developed through an analytical parametric study using a crack analysis procedure that considers the tensile behavior due to the steel fibers and the bond stress-slip relationship between the reinforcing bar and the concrete matrix. With the proposed model, the local yielding of reinforcing bars at a crack can be realistically simulated, enabling reasonably accurate predictions of the tensile behavior of R/FRC members. Analysis results obtained from the proposed model show good agreement with the test results measured by previous researchers.
