Özet
Semi-rigid connections in steel structures represent an essential design element that bridges the gap between fully rigid and simple pinned connections, significantly influencing the structural performance of steel frames. This paper presents a comprehensive analysis of the behavior, classification, and design considerations of semi-rigid connections, addressing their mechanical properties, historical development, and practical applications. The study explores moment-rotation relationships, load transfer mechanisms, and the effects of connection stiffness on structural stability. Additionally, analytical and numerical models for semi-rigid connections are reviewed, highlighting advancements in finite element modeling and component-based approaches. Experimental validation, including moment-rotation testing and structural response assessments, is discussed to reinforce theoretical findings. Case studies demonstrate the successful implementation of semi-rigid connections in industrial buildings, bridges, and large infrastructure projects, showcasing their advantages in terms of flexibility, energy dissipation, and seismic resilience. The paper also examines future trends in semi-rigid connection design, emphasizing the role of advanced materials, computational modeling, and innovative construction techniques. By integrating theoretical insights with practical applications, this research provides a foundational framework for engineers and researchers seeking to optimize the design and performance of semi-rigid connections in modern steel structures.
