Abstract: The semi-interlocking masonry (SIM) system has developed in Masonry Research Group at the University of Newcastle, Australia. The SIM panels dissipate energy through the sliding friction on bed joints of SIM units during earthquake excitation. To model the SIM panel's behaviour numerically some key parameters need to evaluate experimentally. This study investigates the elastic modulus of SIM prism and thrust force for horizontal and vertical arching during out-of-plane deflection. Three types of bricks were used in tests: topological SIM, mechanical SIM, and without interlocking bricks. In addition, the prisms of topological SIM bricks comprising three and five bricks have been used to find out the mechanical properties of units. This paper presents the results of 18 arching tests: six tests with topological interlocking, six tests with mechanically interlocking units, six tests with ordinary bricks, and 11 prisms of topological SIM bricks for compressive and modulus of elasticity test.

Keywords: semi-interlocking masonry; SIM; elastic modulus; slip joints; horizontal arching; vertical arching; out-of-plane.
