Modeling of Timber-Concrete Composite Structures Subjected to Short-Term Monotonic Loadin

Timber-concrete composite (TCC) is an innovative and efficient construction material which exploits the best properties of timber and concrete. The presence of shear connectors enables the two dissimilar materials to act together as a whole, resulting in an increase in global stiffness as well as load-carrying capacity. As this composite material is becoming increasingly more popular in the construction industry, there is a need to develop an analysis tool which has general applicability to timber-concrete composite systems with variations in loading schemes, specimen configurations, materials, and types of shear connectors. VecTor2, a 2D nonlinear finite element program developed at the University of Toronto for the analysis of reinforced concrete structures, has the potential to be extended to analyze plain timber and timber-concrete composite structures, provided that an appropriate timber constitutive model is implemented.;A generic 2D nonlinear finite element model is proposed in this thesis, and is verified through extensive numerical simulations of six experiment series carried out by researchers around the globe. Good agreement between experimentally observed behaviour and numerical simulations were generally obtained.
