Abstract
This paper addresses the issue of composite behaviour between structural steel beams and precast concrete planks for multi-storey buildings. Whilst it is becoming increasingly more common to use precast concrete planks in the Australian building construction, the benefits of composite behaviour have not yet been fully realised with these systems. The main advantages of this form of construction are that the precast concrete units and the steel frames are both derived from manufacturing technology and share the quality control, accuracy and reliability of factory production and thus lead to savings associated with reduced construction times. This paper provides an initial investigation into the issues that need to be resolved for the shear connection in order to establish composite action. The paper outlines various structural forms including hollow-core or solid precast concrete construction manufactured in Australia and considers the behaviour and design of these systems for ultimate loads. Furthermore, the paper provides some very preliminary test results which were undertaken to consider the behaviour of shear connectors adopting the various accepted practices for construction as outlined in Australia. These should prove useful for structural engineers until a more comprehensive experimental program which considers a whole range of parameters is completed.
