摘 要: 以方钢管混凝土柱与钢梁连接节点的抗震性能为主要研究对象,介绍几种常用的节点形式及规范推荐的设计方法,针对国内外节点抗震性能试验现状讨论存在的问题。讨论结果表明:方钢管混凝土柱与钢梁节点普遍具有较好的抗震性能,但大多数试验结果只能定性判断节点承载力和抗震性能,无法获得节点核心区的真实性能,且针对节点性能的评定缺乏明确适用性指标。另外,由于节点形式多样,难以建立关于此类节点抗震性能的试验数据库,从而制约了其发展。
关 键 词: 工程结构;抗震性能;综述;方钢管混凝土柱;钢梁;节点

Abstract: This paper mainly studies seismic behavior and performance of the joints of concrete filled square tubular column to steel beam, and introduces several common types of the joints and design method recommended by China specification. Furthermore, it studies problems based on the previous tests of seismic behavior of the connection are commented. And the results show that the seismic performance of joints of concrete filled square tubular column to steel beam is generally good, but in most of the test, results were judged qualitatively with very little information about the joint core area, and now there is no definite standard to evaluate the behaior of joint. Moreover, because of the diversity of joint form, it is hard to erect a database about the seismic behavior of this kind of joint, which hinders its development.
Key words: engineering structure; seismic performance; reviews; concrete filled square tubular column; steel beam; joint
