The objectives of the research programme were to assess the range of connections presently used to join cold-formed sections and to identify those that could be further developed for common use. Standard lap shear tests and joint bending tests with different fasteners were carried out to examine the structural performance of the fastenings. Their usage and potential for site fixings were also assessed. Design values were compared with the test results. Different ways of mechanical enhancement in connections between cold-formed sections were also investigated. Lap shear tests with different forms of swaging around fasteners were carried out. Practical connection configurations between cold-formed sections in buildings were also examined. Connections with web cleats and joist hangers were tested to investigate their structural performance up to failure. Based on the findings of the tests on the connections with joist hangers, a new form of connection component, referred to as the channel hanger, has been developed through rational design. Confirmative tests on channel hangers were also carried out. Design methods for connections with web cleats, joist hangers and channel hangers have been formulated after calibration with the test results.
