Description
Summary:In view of the development of heavy timber seismic resistant structures, in the context of modern seismic design approach based on the mechanical triad of strength, stiffness and ductility, the dissipative capabilities should be delegated to specific devices, considering that timber mechanical behavior is typically fragile. With reference to the structural type of Moment Resisting Frames (MRF), steel links located at the ends of the beams are very promising solutions. In this regards the paper focuses on a beam-column timber joint equipped with steel links for dissipative heavy timber seismic resistant MRF, inspired by a reference experimental campaign on timber beam-to column assemblages conducted at the University of Trento. A refined finite element numerical model of the joint is set-up through the Abaqus software (v. 6.14) and efficiently calibrated on the basis of the experimental evidences. A very good numerical simulation of monotonic tests carried out in Trento has been achieved. The FE model would be a powerful tool for carrying out parametrical analysis aiming at the characterization of the mechanical properties and the optimization of the system, for the application in seismic resistant timber MRF.
