Abstract:

Interest in timber-concrete composite (TCC) floors has increased over the last 20-30 years. Since the 1990's, TCC solution is seen as a viable and effective alternative to conventional reinforced concrete and/or traditional timber floors in multi-storey buildings. TCC technology relies on timber and concrete members acting compositely together. Thus, the strength, stiffness, location and number of connectors play a crucial role for the composite action and determine the structural and serviceability performance of TCC solutions. To date, conventional concrete (CC) has been used in most investigations on TCCs. Also, there are only few researches about the effect of concrete properties on the structural behaviour of TCCs. Self-compacting concrete (SCC) is highly workable and can be compacted without use of conventional vibration methods. As such, there is a potential for application of SCC in difficult to access areas or areas where complex formwork make it difficult to use conventional vibration methods. University of Technology Sydney has investigated TCC solutions since 2007. The investigation presented in this paper focuses on utilising mechanical fasteners for their ductility and stiffness to compositely attach a SCC slab to a timber beam and to investigate the effect of use of SCC on the behaviour of such connections. The experimental aspect of the research consists of push-out tests and aims to characterise slip modulus and load capacity. The responses of the specimens are also compared to that of TCC systems with conventional concrete. The failure modes of the connections are also studied.
