Study on the Structural Properties of Steel Reinforced CRC Beam-Cracking Resistance

Abstract:

In recent years, there has been mounting interest in the use of recyled tire rubbers in engineering construction. Crumb rubber concrete (CRC) is made by adding rubber crumbs into conventional concrete. As a new kind of concrete material of energy saving and environment protecting, CRC has many advantages such as lower Young’s modulus, high damp modulus, large deformation, better depleting energy and perfect ability of holding back crack. The research about it at home and abroad mainly focuses on the basic material properties. But, studies on structural behavior of steel reinforced CRC for structure were seldom reported. This paper, based on the existing experiments, analyzed the cracking resistance of steel reinforced CRC beam under static load, and deduced a new crack-resistant moment formula. The calculating results using this formula have good agreement with the experimental results obtained by other researchers. The study shows that the steel reinforced CRC can effectively improve the cracking resistance of structure.
