Also, the study showed that the tension stiffening decreases with the increase of the percentage of the flexural reinforcement ratio. Online capacitor energy (E) and RC time constant calculator to calculate the energy (E) and time constant (RC) in a capacitor for the given voltage across. The comparison revealed that the codes’ equations always consider tension stiffening lying between lower and upper bound of tension stiffening proposed in this study. The resistor value is assumed to be in K ohms, the capacitor in microfarads, and the calculated delay will be in milliseconds. The models include different percentages of flexural steel ratio. In addition, a comparison is carried out among the different codes using four reinforced concrete rectangular models to compare and evaluate the tension stiffening with proposed analytical lower bound tension stiffening and upper bound as obtained by ABAQUS.

Also, a commercial Finite Element Program (ABAQUS 2007) was used to perform non-linear analysis in order to evaluate the total contribution of the tensioned concrete in carrying loads which may be considered as the upper bound of tension stiffening.

A simple analytical procedure is proposed for the determination of forces, stresses and strains acting on a reinforced concrete section subjected to flexure considering the concrete contribution in tension up to tensile concrete strain corresponding to the cracking strength of concrete. Building codes consider the tension stiffening when calculating the crack width of the flexural members.
