Precast concrete structural shear walls (PCSSW) are used to resist lateral loads in medium to high-rise buildings. Generally, PCSSW response is highly dependent on the behaviour of base panel-to-foundation joint. An innovative joining technique is proposed to accelerate construction process and reduce concrete damage possibility during an earthquake event. A non-linear finite element model is developed to capture the effect of the new joining technique on PCSSW behaviour and possible failure modes. This paper is focused on modelling the shear force transfer across the joint. Key parameters regarding mesh, material model, contact definition, and other parameters are identified. The numerical model shows good capabilities in simulating the behaviour and in capturing different governing mechanisms including dowel action and coulomb friction. Since testing a full scale PCSSW to investigate the real behaviour is rather expensive, developing a reliable model that predicts PCSSW behaviour with reasonable accuracy represents a valuable and cost effective tool.
