Research on Seismic Performance of Reinforced Beam-Column Joints of Steel Structures

摘要: 钢结构框架建筑应用十分广泛。钢结构作为一种优质的建筑材料具有轻质高强，施工速度快等优点。为了研究钢结构梁柱节点在抗震方面的性能，通过检索总结国内外相关文献，分析不同形式的加强型节点并梳理相关参数及受力性能，最终得出结果。结果表明：节点加强型钢结构在抗震方面表现良好，节点加强后使塑性铰外移达到“强柱弱梁”的设计原则，有效提高钢结构的抗震性能。最后，对加强型钢结构节点研究进行总结与展望。

Abstract: Steel structure frame buildings are widely applied. As a high-quality building material, the steel structure has the advantages of being lightweight yet high-strength, and enabling rapid construction speed. In order to study the seismic performance of the beam-column joints in steel structures, relevant domestic and foreign literature are retrieved and summarized, different forms of strengthened joints are analyzed, and the relevant parameters and mechanical properties are sorted out. Finally, the results are obtained, and they indicate that the strengthened joint steel structure performs well in terms of seismic resistance. After the joints are strengthened, the plastic hinge is shifted outward, achieving the design principle of “strong columns and weak beams”, effectively improving the seismic performance of the steel structure. Finally, a summary and prospect of the research on the strengthened steel structure joints are carried out.
