Earthquakes represent a critical threat, particularly in seismic zones where the structural integrity of buildings can mean the difference between life and death. Traditional construction approaches, while ostensibly robust, often succumb to debilitating damage post-quake, necessitating costly and time-consuming repairs, or worse, complete rebuilds. These shortcomings have spurred continuous advancement in structural engineering, pushing the boundaries of what is feasible in earthquake resilience to not only enhance safety but also reduce economic losses and expedite recovery times after seismic events.

In response to these challenges, self-centering structures have emerged as a groundbreaking solution. Unlike traditional systems that rely on permanent deformations to absorb seismic energy, self-centering systems utilize specialized devices that enable structures to return to their original positions post-earthquake. This technology not only prevents major damages and associated costs but also significantly shortens recovery times, allowing for quicker reoccupation and reduced disruptions to social and economic activities.

This Research Topic aims to delve into the cutting-edge developments in self-centering technologies and their integration into steel and concrete structures. It seeks to foster theoretical and practical advancements that could redefine seismic resilience through enhanced structural performances and efficiency. To further our understanding and improve the seismic resilience of urban environments, contributions are invited on the following themes:
• Innovative self-centering devices for seismic resilience enhancement
• Breakthroughs in self-centering structural systems
• Experimental investigations into component and structural behaviors
• Strategies for performance-based seismic design and optimization
• Life-cycle cost analysis and resilience assessments for self-centering systems
By focusing on these areas, this topic is slated to not only push forward the technological envelope but also contribute to safer, more sustainable urban development in earthquake-prone regions.
