“…Four-point bending tests were performed on the rectangular notches and sinusoidal notched wave connectors to study the structural behavior of beech-LVL-concrete composite structure (Boccadoro and Frangi 2014). The mechanical properties of different connectors were investigated and some full-scale timber-concrete composite slabs were also tested (Crocetti et al 2015).…”

A timber-concrete composite structure (TCC) is economically and environmentally friendly. One of the key design points of this kind of structure is to ensure the reliability of the shear connectors. The objective of this paper is to study the mechanical property of stud-groove-type connectors and to provide shear capacity equations for stud-groove connectors in timber-concrete composite structures. Based on the Johansen Yield Theory (European Yield Model), some mechanical models and capacity equations for stud-groove-type connectors in timber-concrete structures were studied. Push-out specimens with different parameters (stud diameter, stud length, groove width, and groove depth) were tested to obtain the shear capacity and slip modulus. The experimental strengths were used to validate equations given in the paper. The shear capacity and slip modulus of stud-groove-type connectors was in direct proportion to the diameter of studs and the dimension of the groove. Comparison between the theoretical and the experimental shear strength results showed reasonable agreement. The highlight of this study on shear capacity equations could significantly reduce the push-out tests before investigating the other properties of TCC.

“…Lukaszewska et al [16] , [17] investigated several types of shear connections which can realise the semi-prefabrication of TCC beams. Crocetti et al [18] proposed an effective method to realise the ‘dry-dry’ connection of TCC beam by using inclined screws. Khorsandnia et al [19] also researched several possibilities for the deconstructable TCC beams, and obtained desired structural performances.…”

“…It was found than the interlayer could evidently decreases the slip moduli of shear connections and bending stiffness of TCC structures [22] . (3) The prefabricated concrete slabs could reduce the high creep of concrete during curing [18] . (4) Reduce the pollution on the construction site and improve construction efficiency [23] .…”

“…Although composite concrete-based floors have become very common technologies, the use of non-renewable resources, the high demand of energy for production and transportation and the difficult recycling process impact on their sustainability. Possible other inconveniences are the required curing time, which sometimes can complicate on-site construction; the inherent self-weight of the structural components, which typically affects the costs of transportation; the limited number of prefabricated solutions currently available [17]. As 'dry' alternatives to the above-mentioned concrete-based traditional solutions, more recently timber-timber and steel-timber composite solutions have attracted more attention.…”

8An innovative steel-timber composite floor for use in multi-storey residential buildings is presented. The research 9 demonstrates the potential of these steel-timber composite systems in terms of bearing capacity, stiffness and method of 10 construction. Such engineered solutions should prove to be sustainable since they combine recyclable materials in the 11 most effective way. The floors consist of prefabricated ultralight modular components, with a Cross-Laminated Timber 12(CLT) slab, joined together and to the main structural system using only bolts and screws. Two novel floor solutions are 16steel beams. Specifically, the first proposed composite system is assembled using mechanical connectors whereas the 17 second involves the use of epoxy-based resin. In the paper, a FEM model is provided in order to extend this study to 18 other steel-timber composite floor solutions. In addition, the paper contains the design model to be used in 19 dimensioning the developed systems according to the state of the art of composite structures. 20
