Abstract

The paper reports the outcomes of an extensive research project on timber-concrete composite (TCC) floors at the University of Canterbury, New Zealand. Two phases of the entire programme are described (1) push-out tests on different notched connection systems and (2) first month monitoring of TCC floor beams after construction. A semi-prefabricated TCC floor system that is economical, practical and easy to construct is proposed. An analytical model for strength evaluation of a typical notched connection reinforced with coach screw is presented. Four best connection details were selected and used to design and construct TCC beams for application in medium to long-span office floors. The composite beams are being and will be tested under short- and long-term loading. The experimental results of the first month monitoring of beams after construction are reported and compared with a uniaxial finite element model which was specially developed for long-term and collapse analysis of TCC beams. Overall, the validations were found to be within good accuracy except for some cases with acceptable experimental deviations. Other parameters observed were different construction variables and type of concrete.
