| 摘 要： | 加强环式节点是钢管混凝土柱 -钢梁体系的常见连接形式 ,认识此类节点的受力性能对结构设计至关重要。在国内外已有的试验及理论研究中 ,主要针对钢管混凝土柱与钢梁垂直正交节点 ,而对斜交节点的研究没有报道。通过对 6个多向相交节点的试验 ,分析了斜交节点核心区在静力加载全过程中的应变与转角变化特点。结合试验现象 ,对此类节点的设计提出一些建议 ,建立了加强环式斜交节点的承载力计算经验公式。 |
| 关 键 词： | 组合结构 斜交节点 试验研究 |

| Abstract: | In concrete filled steel tube column with steel beam system, strengthe ning plate ring is widely used, so it is important for engineers to get some kno wledge about this kind of joint. In the past, tests and researches are mainly f ocused on the form of perpendicular joint of column with beam. There has been little study on the multi-dimensions joints by far. On the basis of six concrete filled joi n ts with non-perpendicular elements experiments,a study is conducted on the beha vior of the joints in whole process under static load. Some useful suggestions are g iven for design, and empirical formula for the bearing capacity of this kind of joints is proposed. |
| Keywords: | composite structure concrete-filled joint with non-perpendicular elem ents experimental study |
