Abstract— The seismic performance of adaptive buildings represents a significant advancement in structural engineering, aiming to enhance resilience and safety during earthquakes. Adaptive buildings utilize innovative technologies such as base isolation, energy dissipation systems, and real-time control mechanisms to dynamically respond to seismic forces. These structures are designed to adjust their stiffness, damping, and mass properties in real-time, optimizing their performance under varying seismic loads. This adaptability reduces structural damage, minimizes energy dissipation, and ensures occupant safety. Recent studies and experimental results demonstrate that adaptive buildings outperform conventional structures in terms of displacement control, acceleration reduction, and overall seismic energy management. However, challenges such as high initial costs, complex design requirements, and maintenance of adaptive systems remain. In this research work the principles, technologies, and performance metrics of adaptive buildings, highlighting their potential earthquake-resistant design and contribute to sustainable urban development for high seismic zone.

The seismic performance of adaptive building systems represents a significant advancement in earthquake engineering, aiming to mitigate structural damage and enhance the safety of occupants. Adaptive systems differ from conventional static structures by incorporating real-time monitoring, feedback loops, and dynamic response mechanisms that adjust to external forces during seismic events. These systems include technologies such as base isolation, tuned mass dampers (TMDs), active and semi-active control systems, and smart materials (e.g., shape-memory alloys and magnetorheological dampers).

 Advantages of adaptive building systems include improved energy dissipation, reduced inter-story drift, and greater flexibility in structural design. These systems are designed to respond autonomously to seismic loads, adapting their stiffness, damping, or mass distribution to counteract ground motions. Additionally, the integration of sensors and control algorithms allows real-time structural assessment, enabling rapid post-earthquake evaluations and minimizing downtime. Future advancements aim to develop more cost-effective, scalable adaptive solutions suitable for both new constructions and retrofitting existing buildings. This research underscores the transformative potential of adaptive building systems in modern seismic design, contributing to safer, more sustainable, and resilient built environments.
