SPLITTING BOND FAILURES OF LARGE DEFORMED REINFORCING BARS

Tests have been carried out to study splitting bond failures of large bars having a nominal diameter of 51 mm (2 in.) and various deformation patterns. The test setup, referred to as the modified cantilever type, permits the development of a stress distribution in the test specimen similar to that to be found in the shear span of beams. The main variables studied were: clear cover, number of stirrups, bond/shear ratio, loading history, including alternating pull-out, push-in loads, and bar deformation. Based on the test results, recommendations are provided for application of large bars to the design of earthquake-resistant framed structures. /Author/
