A Summary of Research on Seismic Behavior of Beam-Column Joints of Weakened Steel Structures

抗震性能已成为目前钢结构领域的重要指标，基于国内外相关文献的分析，对学者们做出的削弱方式分为梁翼缘削弱，翼缘开孔和腹板开孔3大类进行讨论，探讨了相关参数对梁柱性能的影响，同时提出不同削弱方式的钢结构梁柱节点可能存在的问题，并对该类问题提出了相应的建议，以期为削弱型钢结构梁柱节点抗震性能的研究提供参考。Seismic performance has become a crucial indicator in the field of steel structures. Based on the analysis of relevant literature both domestically and internationally, this study discusses three major categories of weakening methods proposed by scholars: beam flange weakening, flange opening, and web opening. It explores the impact of related parameters on the performance of beam-column connections, identifies potential issues associated with different weakening methods in steel beam-column joints, and provides corresponding recommendations. The aim is to offer references for research on the seismic performance of weakened steel beam-column joints.
