This reprint synthesizes contemporary advancements in seismic analysis and design methodologies for civil infrastructures, encompassing buildings, bridges, and associated structural systems. The contributions compiled herein address a spectrum of cutting-edge topics, including base isolation systems, energy dissipation dampers, soil-structure interaction, and corrosion-induced degradation. Methodologically, the studies employ multidisciplinary approaches spanning theoretical frameworks, finite element-based numerical simulations, and experimental investigations under quasi-static and shaking table testing.
