• Numerous analytical techniques, analytical theories, and analytical/design models have been proposed for the rational shear designs and shear behavior examinations of reinforced concrete beams. However, since shear design regulations in design codes are primarily based on experimental observations along with the elastic beam theory, the regulations may not accurately represent the true shear behavior of general reinforced concrete beams. Accordingly, much attention has been focused on the development of a general and consistent model or method. In this study, the strength and behavior of four reinforced concrete beams tested to shear failure were estimated using a nonlinear strut-tie model approach. Based on the strut-tie model analysis results, the validity of the nonlinear strut-tie model approach in the reasonable design of reinforced concrete beams and in the accurate examination of many shear-related failure phenomena was evaluated.
