Recently, research and development of smart materials and structures for civil engineering applications have attracted increasing attentions from researchers around the world. Smart devices can be incorporated into civil structures as smart structural members with intelligent and controllable capacities for optimally detecting and reacting to the internal and external changes. Within the smart devices, magnetorheological (MR) based devices are one of the most promising smart devices to be considered for civil structures. Tills paper presents a novel design of a new-generation MR pin joint with high-torque capacity. An innovative design and analysis of MR pin with radial slots at the surface of the rotary plate is proposed. Theoretical modelling is undertaken based on the material, mechanical and magnetic analyses. Parametric analysis is conducted to optimise the shape, width and depth of the slots to best accommodate the design objectives.
