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 = {The purpose of this research is to analyse the long-term deformations of reinforced concrete beams made of recycled coarse aggregates (RCA), using four different replacement ratios, 0%, 20%, 50% and 100%. For said purpose, three different loading stages were carried out: firstly, loading and sustained load for 1300 days, secondly, unloading and recovery where the deformations were registered over a one year period, and lastly, testing the concrete beams up to failure in order to analyse the effect of recycled aggregates on pre-cracked concrete members. The results led to the analysis of deformations under sustained load, as well as those produced after removing the load and the performance of pre-cracked members, while identifying the effect of recycled coarse aggregates on concrete performance in terms of plastic deformation, recoverability and concrete stiffness, and also on structural design.},
