A new model for predicting crack width with different percentages of reinforcement and concrete strength classes

摘要

This paper describes a new model for predicting crack width in presence of different percentages of rein- forcement 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 submit- Ted 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 man distance between Cracks.
