Experimental Study on the Shear Behavior of RC Beams with Corroded Stirrups
Source abstract
Abstract
The shear behavior of corroded reinforced concrete (RC) members is an urgent problem to be solved. The study carried out an experimental program on the shear behavior of 21 beams, which included 3 un-corroded RC beams and 18 corroded ones. Both shear span-to-depth ratio and corrosion degree influencing the shear strength as well as failure patterns were discussed in detail. This paper aims to contribute to a better understanding about the effect of corrosion on the shear behavior of corroded RC beams. The test results show that corrosion of stirrups reduces the aggregate interlock capacity of concrete, also the ductility and shear strength of the flexural members. In shear-compression zone, cracks caused by corrosion of stirrup have a predominant influence on shear strength; Failure modes of RC beams depend largely on shear span-to-depth ratio and are little affected by corrosion of stirrups. Based on the results of experiments and the limit equilibrium theory, the calculation model of shear capacity for corroded simply supported RC beams is proposed, which has a simple form and clearly physical conception.
