DEFORMATION AND FRACTURE OF MASONRY UNDER COMPRESSIVE LOAD

The paper presents the experimental results on masonry fragment exposed to static load. The diagonal loading scheme is used allowing to create main tensile stresses in the middle of masonry and estimate their impact on its fracture. Noncontact techniques are used for the surface deformation measurements that allow detecting the sequence and the nature of crack propagation during fracture. Investigations show that crack initiation is induced by tangent deformations in vertical joints of masonry. The load increase provides main tensile deformations that induce the fracture of masonry.

Keywords: masonry; surface deformation; vibration velocity; crack formation.
