Abstract

This contribution is addressing the investigation on the effect of axial tension on the shear strength of reinforced concrete beam elements without stirrups. The paper presents the results of a test program of 15 beams without stirrups that differed from each other mainly by the intensity of the axial tensile force N. During the tests, cracking was measured by Digital Image Correlation technique to identify the crack evolution mechanisms. After some consideration on the resisting mechanisms, the experimental results are compared with several code formulas to predict the shear strength V_Rc. Then an empirical formula is proposed for the variation of V_Rc between its two limits: the values for N = 0 and for V_Rc = 0 at the ultimate limit state of axial tension. This formula makes it possible to easily design for shear and tension.
