Abstract:
From published reports, a database of 1200 tests was compiled to examine the effects of loading type and position of the load on the shear strength of reinforced concrete beams. Twenty-four additional tests were conducted to examine the differences in shear response due to concentrated and uniform loads where data were lacking. Experimental results indicated that shear strength can be affected by the type of loading. It was observed that a significant number of beams subjected to concentrated loads applied between 2d and 6d from the face of the support failed at loads below the nominal strengths calculated using current design provisions. A simple change to the current ACI 318 shear design procedure is proposed for beams subjected to concentrated loads.
