Innovative Plastic Hinge Relocation Technique in Steel Moment Connection

Abstract

This paper presents a novel plastic hinge relocation technique in steel beam column joint with replaceable fuse connection in beam segment. The main objective of this study is to analyze the behavior of the beam member with different cross sections and orientations, and investigate the impact of removing the gap between beam segments to identify an effective specimen that can enhance the moment capacity and performance of the joint and reduce the risk of brittle failure. Finite element analysis (FEA) was conducted using ANSYS software to evaluate the performance of the proposed technique under cyclic loading conditions according to the AISC protocol (AISC in Seismic provisions for structural steel buildings. American Institute of Steel Construction, 2010 [1]), and the hysteresis curve was obtained. The results of this study provide insights into the strength and ductility of the proposed steel beam column joint with replaceable steel fuse angle connections. The proposed technique has the potential to enhance the resilience of structural systems, thereby improving public safety and reducing economic losses. The findings of this study are relevant to the civil engineering industry and can contribute to the development of innovative and resilient structural systems that can withstand extreme events and improve the safety and sustainability of modern infrastructure.
