Alternative methods of stone cladding : an investigation of the shear strength of the joint between Globigerina limestone veneer and the backing support for various cladding systems

Abstract

Locally, no research has as yet been carried out on stone cladding systems, one of the reasons probably being their relatively only very recent popularity. Abroad, the situation is different since experimental work has actually been carried out, however the available test results on stone veneer do not necessarily apply to the local globigerina limestone, which has different physical and mechanical properties. Thus, in order that local stone be used in alternative ways, such as cladding, there must be proper background research to verify its structural safety. The aims of this dissertation were hence threefold. Initially, the type and number of alternative systems locally feasible were established, and laboratory techniques for their subsequent investigation were set out. Secondly, a test rig had to be designed which was to simply and effectively illustrate the behaviour of the joint in shear and determine the failure load where possible. Finally, an analysis was to be made to compare the different systems and to set up a range of shear loads which would ensure the strength of the joint.
