- Description
- An innovative masonry building system is being developed in the Centre for Infrastructure Performance andReliability at The University of Newcastle, Australia for seismically vulnerable regions as an alternative totraditional masonry panels. This system consists of mortar-less masonry panels made of semi-interlockingmasonry (SIM) units capable of relative sliding in-plane of a panel and inter-locked to prevent sliding out-of-plane of a panel. These special panels have significant energy dissipation capacity due to friction onsliding bed joints between the SIM units during a seismic event. As SIM is a new masonry system, it isimportant to study the load-displacement behavior. In this study, a new approach is developed to idealizethe load-displacement response of SIM infill panels. The force-displacement response of SIM panels can bedescribed by two equivalent bilinear relationships. In order to evaluate the seismic behavior of framed SIMpanels, a series of three SIM panels were built with topological SIM units and have been tested by subjectingthem to cyclic in-plane displacements up to 100mm. It has been shown for the current study that besidesshear displacement and energy dissipation capacity, the initial slope of bilinear relationship should be takeninto account as a governing parameter when evaluating the force-displacement response of SIM panels inlarge displacement.
