EVALUATING AND PROPOSING PREDICTION MODELS OF SHEAR CRACK WIDTH IN CONCORETE BEAMS

Abstract

 This paper presents a comprehensive review on the available prediction models in the literature to estimate shear crack width in reinforced and prestressed concrete members by comparing shear crack openings calculated from prediction model with those obtained from seven experimental investigations to evaluate their accuracy together with effectiveness of factors considered. As a result of this study, the models for the prediction of shear crack spacing and width in reinforced and prestressed concrete beams are proposed. The proposed models show a better correlation with all the test results compared to the other prediction models. The models can predict both average and maximum shear crack width and are applicable to fatigue loading.
