Analysis on Structural Behavior of Semi-Rigid Joint in Steel Frame

In the field of modern construction, steel structures have become the primary material of choice for design and construction. As a novel type of steel structure connection, the semi-rigid connection displays enhanced anti-collapse capabilities and energy dissipation characteristics under dynamic loading, offering significant research value and promising application prospects. Semi-rigid connections possess a combination of stiffness, ductility and load capacity, and are relatively straightforward to construct. These are practical and economically viable connection methodologies. This paper presents a summary of the specifications and classifications of semi-rigid joints as outlined in domestic and international literature. It also provides an overview of the characteristics and types of semi-rigid joints used in steel structures, along with an examination of the research methods and findings related to these joints. The paper aims to offer insights and guidance for the advancement of knowledge in the field of semi-rigid joints in steel structures, including their research, design, and practical applications.
