A new model for predicting crack width with different percentages of reinforcement and concrete strength classes
Abstract This paper describes a new model for predicting crack width in presence of different percentages of reinforcement and concrete strength classes that became from 30 to 80 MPa. The theoretical analysis is used to interpret the results of experimental trials on reinforced concrete ties submitted to tensile forces without inducing any yield in the bar. The purpose of the investigation was to study and predict the crack width using as base parameters the stress in the steel at crack and the mean distance between cracks. The calculation model is based also on a precise mechanical characterization of the concrete's effective tensile strength (i.e. in presence of reinforcement) and give a sufficiently user friendly procedure to determine crack width without taking into account the concrete and steel deformation, which are difficult to measure.
