- Description
- The Semi Interlocking Masonry (SIM) system has been developed in the Centre for Infrastructure Performance and Reliability at The University of Newcastle, Australia. This system is designed for the construction of earthquake-resistant in-fill panels in framed structures. SIM panels dissipate earthquake energy through the sliding friction on bed joints within a panel as the frame is distorted in-plane with the infill panel. The compressive strength and Young’s modulus of SIM are important design properties, particularly where SIM is used as a confined masonry system. Different design and testing standards proposed various methods to test the compressive strength and Young’s modulus of traditional mortared masonry. However, there is no standard testing method/protocol for a mortar-less masonry like SIM. This paper presents a new protocol for testing the compressive strength and Young’s modulus of SIM. Eight and three specimens of mortar-less SIM prisms contain 3-bricks and 7-bricks, respectively, were tested. Linseed oil-based putty was used on bed-joints as joint filler. It is used in SIM to improve buildability, thermal insulation, and water resistance. The required curing time for the putty was investigated first in the preliminary testing program before the compressive tests. The test results indicate that the sufficient curing time for linseed oil-based putty is about 5 days, the average compressive strength of prisms is 5.46 MPa, and Young’s modulus of prisms is approximately 3233 MPa.
