Project title
3d printed shear connector for steel-concrete composite structures
Project abstract
This project aims to investigate the development of novel shear connectors for steel-concrete composite structures using metal additive manufacturing technology. Traditional connectors (such as studs with heads) are constrained by manufacturing limitations and lack potential for geometric optimisation. By leveraging the design freedom offered by 3D printing, combined with machine learning and topological optimisation, new shear connectors are designed and iterated. This study combines experimental testing with finite element modelling to evaluate structural performance, including shear capacity, load-slip behaviour, stiffness and failure modes. Push-through tests conducted in accordance with European Standard EN 4 are used to validate the proposed designs, whilst experimental data is utilised to calibrate the numerical models. This research also seeks to establish a design framework for optimised, high-performance shear connectors with potential for demountability in future composite structures.
