THE EFFECT OF CONFINING REINFORCEMENT ON THE DUCTILITY OF REINFORCED CONCRETE BEAMS

Abstract

The report discusses some means of improving the compressive strain capacity of concrete to provide the ductile members or connections which will safely allow for formation of the plastic hinges assumed in designs based on collapse and energy-absorption concepts. The primary objectives of this investigation were to evaluate the effects of various types of confining reinforcement (helices, plane and tubular meshes, and rectangular ties) on the static stress-strain characteristics of rectangular concrete prisms tested in uniaxial compression, and, based on the results of these tests, determine the effectiveness of using selected confining reinforcement in the compressive zone of reinforced concrete flexural members to increase their ultimate strength and ductility.
