AB - The shear strength of RC beams is significantly enhanced by arching action when loads are applied within twice the beam effective depth (2d) of supports. Many studies have investigated this phenomenon for single span simply supported beams with single point loads applied to their compression face within 2d of supports. However, very little research has been carried out into shear enhancement in beams with several point loads applied within 2d of the support. Previous research into this problem has focussed on situations where pairs of equal point loads are applied to the compressive face of the beam. This research compares the behaviour of beams loaded with pairs of concentrated loads applied, within 2d of the support, to either the tension or compression face. The research was motivated by differences in the geometry of strut and tie models for each case, which does not appear to have been previously investigated. The behaviour of the beams during tests was recorded with Digital Image Correlation (DIC) which captured the full displacement field of the beams. The displacement field was analysed to determine the crack kinematics. This enabled the contributions to shear resistance of aggregate interlock and dowel action to be determined. The paper summarises the results of the experimental program and describes insights into shear resisting mechanisms gained from studying the crack kinematics obtained from the DIC. The influence of the loading face being in tension or compression is also discussed.
