The primary purpose of this experimental investigation is to obtain the cyclic shear response in a cracked concrete, and to accumulate the necessary information that applies to nonlinear finite element analysis. The biaxial testing device, the vertical and horizontal load as well as displacement can be independently controlled by closed-loop servo systems, has been developed in order to establish the shear behavior in cracked concrete. The shear tests on specimens containing narrow cracks (0-0.8mm) have been carried out keeping normal displacement across the crack surface constant to study the effect of cyclic loading. The relation of normal and shear strsses to crack width and sliding displacements was discussed, and some equations which give the shear response and shear retention factor have been derived from the experimental results.
