Abstract:
The modified compression field theory is used to predict the response of reinforced concrete members subjected to combined shear and axial tension. It is predicted that even members containing only longitudinal reinforcement have considerable postcracking shear capacity provided that the reinforcement is capable of preventing excessive widening of the cracks. Tests of 24 such specimens are used to verify these predictions. Based on the analytical study, the experimental program, and a review of previous experimental studies, it is concluded that the current ACI design procedures for members in combined shear and tension are excessively conservative.
