“…It is also worth to notice that timber members sizes can be determined by the number and type of connectors rather than by the strength requirements for members. With regards to Moment Resisting Frames (MRF), several experimental studies have been recently carried out on common timber beam-to-column joints, aimed at evaluating the strength and stiffness capabilities [1][2][3][4][5][6][7][8][9]. However, both in national and international standards, there is not a method that allows to identify the mechanical behaviour of timber connections.…”

The performance of timber structures is greatly influenced by the capacity of the connections, in terms of both strength and stiffness, as well as ductility. Reliable estimations of the structural behaviour of timber buildings is possible through a full understanding of the joint behaviour. At present there is not a standard method that allows to identify the mechanical behaviour of timber connections. To fill this gap, in this paper, a procedure for the classification in terms of strength and stiffness of beam-to-column joints in timber structures is presented. The method is inspired to that one related to steel connections according to Eurocode 3. Then, with reference to a number of experimental studies available in the scientific literature on several timber beam-to-column joints, the proposed classification method is applied on typical configurations, evidencing that common joints can be classified as pinned or semi-rigid.

“…It is therefore possible to take advantage of the knowhow on steel constructions related to the seismic design criteria, according to the approach based on the ductile and dissipation requirements (capacity design), adopting necessary adaptations corresponding to the peculiarities of timber, which should be based on the calibration of the fundamental parameters. With reference to the structural types of Moment Resisting Frames (MRF), steel links located at the ends of the beams [5][6][7][8][9][10][11][12] have the function of ductile fuses, where the plastic hinge in bending is concentrated, while the timber members should be designed with an adequate overstrength, to remain in elastic field. Recently Montuori and Sagarese [9] have applied the steel reduced beam sections, commonly proposed for steel MR frames [10,11], to timber beams.…”

“…The mechanical characterization of the joints is carried out through monotonic numerical analyses, on refined FE models, already calibrated upon past experimental tests [8], by means of the structural calculation program ABAQUS FEA (2019). As a result, the numerical F-u (vertical force-displacement) and M-(bending moment-rotation) curves obtained are compared to evaluate the capabilities of the joints and the adequacy of the proposed design criteria.…”

For the design of dissipative heavy timber frame structures, in the context of modern seismic design approach based on the mechanical triad of strength, stiffness and ductility, brittle timber failure modes can be avoided by integrating hybrid timber-steel system into modern timber connection technology. Thus, the overall seismic performance of timber structures can be improved, entrusting the dissipation function to ad hoc conceived devices, like steel links. With reference to the structural type of Moment Resisting Frames (MRF), steel links located at the ends of the beams are able to provide a significant dissipative capacity, by means of cycles of plastic deformations, while timber members and steel connections, to be designed with an adequate overstrength as respect to the link, behave in elastic field. In this regards, the paper presents the capacity design and the mechanical characterization through monotonic numerical analyses of two different timber beam-to-column joint with steel link for MRF structures, consisting of a timber beam and a steel link connected each other by means of a stiffened end-plate and glued-in steel rods. The proposed design criteria of the joint are validated through the evaluation of performance, by means of nonlinear pushover analyses on the joint refined FEM models, in terms of key parameters, such as ultimate resistance, stiffness, rotation capacity and failure modes. The numerical results confirm the plastic deformation of the link, which large dissipative capacity of the joint corresponds to.
