abstract = {Timber-Concrete Composite (TCC) systems are one of the most interesting strategies for slab construction, both for structural performance and environmental considerations. In the latter sense, some research proposed the use of recycled aggregates and locally sourced timber, as well as the reduction of adhesive consumption. This paper analyses the performance of a TCC system in which the timber-concrete connection is achieved by drilling holes in the web, the concrete contains 20% recycled aggregates, and Cross-Laminated Timber (CLT) made from locally source timber is used. Four-point bending tests were developed with a span of 6 m and a height to span ratio of 1/20. In addition, 3D FEM models were calibrated with the experimental results, and used for a better understanding of the failure modes. The samples showed a strength between 4.22 and 4.83 times that required for loads of public use. Furthermore, in service situation they showed a stiffness that amply satisfies the usual regulatory requirements, with deflections between 1/664 and 1/770 of the span. In addition, the ultimate deformation was found to be approximately 6.4 times the service deformation, suggesting sufficient ductility for use in building structures.},

abstract = {Timber-concrete composites systems offer major structural advantages, as well as additional benefits in terms of sustainability in comparison with only-timber or only-concrete solutions in building work. This paper describes the behaviour of shear connections for a new and simple construction system. It is based on the transmission of shear forces between the two layers of the system through perforations in the wooden boards, without the necessary collaboration for additional connecting elements (fasteners, adhesive or notches). Tests were performed to analyse how the behaviour of the shear connectors was affected by the arrangement of the boards (single or separated), the type and distribution of the perforations and the use of slab reinforcement. The experimental results indicate that this solution has high strength values, with very high service stiffness and ductile failure when at ultimate state, which enables a high level of composite action for connection design. The stiffness coefficient varies from 283.5–887.7 kN/mm per metre. The test pieces with separated boards and reinforcement bars showed the best results, regardless of the size and arrangement of the holes in the boards.},
