Arches which are the carrier systems of historical structures were constructed as four basic geometrical shapes; circular, basket handle, sharp point and flat types. Arches can only carry compressional loads and they transfer these loads to right and left sides. This phenomenon is known as arching effect. Arch material and geometry determine the ability of arches load transfer, in other words its load carrying capacity. In this study, three circular arches were constructed with smooth interface - mortar, smooth interface without mortar, interlocking interface with mortar block contact properties. These arches were loaded uniformly until failure is occured. Each arches load-deformation and total energy consumed-deformation graphs were drawn. According to test results although the arch constructed by using interlocking interface with mortar has the highest load carrying capacity, it was determined that the arch constructed using smooth interface with mortar has the highest performance because of its superior deformation energy consuming capacity with respect to other arches.
