Abstract

Mortar-free interlocking structures are being considered a viable replacement of conventional masonry structures due to their benefits like cost-effective, easy to build. But, the joints among the elements of interlocking structures still need a comprehensive methodology to provide feasible connection type due to use of various interlocking block shapes. Thus, the aim of this literature research is to comprehensively review the joint locations in interlocking structures and type of connections used in other structural systems. This is accomplished by focusing on articles published in highly reputable journals. Interlocking structures require adequate horizontal and vertical connecting mechanism at joint locations due to nature of interlocking block shape. These connections act as restraining elements when structure tends to deform due to lateral loading. The stress concentrations occur at the adjacent surfaces of blocks and at joining locations of elements which are further released in the form of dissipated energy. Interlocking block surfaces resist local failure by resisting sliding over leading to shape deformation. However, connections resist global displacement of structure by resisting lateral movement of individual interlocking block elements in the form of edge confining restraints or in the form of reinforcing rebars. Thus, the role of connecting mechanism in mortar-free interlocking structures is critical for the stability and robustness of the structure.
