Abstract
The design of seismic-resistant structures represents one of the most relevant challenges in structural engineering, with the goal of minimizing the destructive effects of earthquakes. This thesis improves structural safety and makes the analysis of energy dissipation devices more precise and accessible through innovative aspects. A first innovative aspect is the unique classification of energy dissipation devices based on their hysteretic behaviors. This classification distinguishes between rate-dependent and rate-independent devices, providing a detailed picture of their dissipation characteristics and capabilities. The thesis also develops advanced algorithms for parametric identification of hysteretic models, implemented in MATLAB. These algorithms provide an efficient and accurate method for calibrating model parameters from experimental data. The innovation lies in the ability to significantly reduce the computational burden by identifying parameters quickly and accurately, ensuring simulations that faithfully reflect the real behavior of devices. Another relevant contribution is the validation of the Vaiana-Rosati Model (VRM) in a finite element analysis environment, demonstrated through simulations reproducing simple and complex hysteretic loops. Finally, the application of VRM in nonlinear dynamic analyses on reinforced concrete structures equipped with dampers demonstrates the effectiveness of the devices in increasing seismic resilience. The results show a significant reduction in displacements, velocities, and accelerations, underscoring the importance of integrating advanced models and innovative dissipators into seismic-resilient design.
