Seismic Hysteretic Steel-Based Systems to Enhance the Resilience of Precast Structures

The research is centered on utilizing passive-based hysteretic devices to enhance the seismic performance of precast structures. The investigated devices comprise hybrid systems that combine U-shaped metallic elements with supports, shock transmitters, and bracing systems. These systems are chosen for their adaptability and reproducibility across various scales and applications, such as bridges and buildings. Through experimental testing and numerical analyses, these devices have been validated and shown to exhibit high performance across different geometries and structural capacities. Specifically, the studies presented aim to enhance the resilience of various precast typologies, including frame systems, bracing systems, and coupled walls, through the implementation of the proposed devices.
