Title: Splitting Bond Failures of Large
Deformed Reinforcing Bars
Author(s): Shiro Morita and Tetsuzo Kaku
Publication: Journal Proceedings
Appears on pages(s): 93-110
Keywords: beams (supports); bond (concrete to reinforcement); cover; cracking (fracturing);crack propagation; deformed reinforcement; failure; loads (forces); shear properties; slippage;stirrups.
Abstract: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.
