Development of Beam-Column Connection in Special Moment-Resisting Frame Steel Structures
Following the Northridge and Kobe earthquakes, there has been a significant focus on developing earthquake-resistant steel beam-column connections. Two approaches have been utilized, one involves using the beam as a fuse, while the other involves additional members as sacrificial elements. While both methods have shown good seismic performance, it is crucial to ensure that structures are designed and built sustainably and resiliently that can be easily and quickly repaired after an earthquake. The beam as a fuse element performs well, but it cannot be repaired once it undergoes plastic deformation. The design of steel frame structures seems to be experiencing a conceptual shift. The current approach is no longer just about earthquake-resistant structures, but how to create structures with ease of repair if an earthquake occurs. A step that has been widely developed is the use of additional elements in connection components as fuses. Various types of connections have been developed, including steel hysteretic dampers, hourglass-shaped steel that utilizes yielding with a bending mechanism, steel slit dampers and friction-slip mechanisms that rely on shear yielding, and interlock systems that depend on the bearing resistance of interlocking parts. This paper reviews the development of beam-column connections that have been evaluated and implemented thus far. The study was conducted by examining previous research on beam-column connections and considering their seismic behavior. The paper also provides recommendations for new types of beam-to-column connections that have the potential to be further improved and developed, namely by utilizing the replaceable interlock system. Based on the interim findings of the study, it has been determined that the connection system is effective in withstanding earthquakes. Additionally, the connection configuration has been designed in a manner that ensures failure only occurs in the fuse elements while the main components are still elastic even when the maximum strength is reached.
