- Description
- Abstract: The Semi Interlocking Masonry (SIM) building sySlem is being developed in the Centre for Infrastructure Performance and Reliability at The University of Newcastle, Australia. In seismic areas SIM can be used in the form of mor1ar-less engineered pallets, which have significant energy dissipation capacity due to the sliding friction between bricks induced during an earthquake. Mortar-less joints of SIM could be dry or could have some non-adhesive grip filler for improving SIM'5 water penetration and thermal insulation. This paper focuses on the experimental investigation of frictional capacities of three different brick surfaces (dry surface, surface with linseed oil based putty, and surface with rubber foam tape) at realistic boundary conditions and loading regime. To do so, a modified couplet shear test was used. The constant pre-compression typically found in a masonry panel was applied by means of the static gravity loading. It is intended to simulate sliding between bricks due to earthquakes over service life, 160 sliding cycles or ±1.0 mm relative displacement were applied dynamically. The load-displacement history was recorded. The paper reports the results of this testing program in terms of the friction coefficient and the energy dissipa1ion evolution for each type of joint.
