摘要：
This report describes the experimental work and numerical and analytical modelling of composite constructions consisting of a timber beam, a steel fibre reinforced concrete slab and shear connectors. The main aims of this work are the identification and the verification of parameters of contact elements that represent the connection, so that they could be used in complex numerical models of whole systems to explore the use of steel fibre reinforced concrete slab with timber beams and investigate the behaviour of the load floor structure using Ansys models. The results obtained in the numerical simulations are compared with the results obtained from push-out tests and the beam test. Six push-out tests and one beam test were conducted to determine the stiffness and the shear bearing capacity of the connection system under the application of steel fibre reinforced concrete. Based on the tests and FE modelling, the analytical model is prepared for the connectors of timber and steel fibre reinforced concrete composite beams.
