新型薄壁钢-混凝土组合结构节点试验研究

Experimental Study for the Joints of New Thin-walled Steel-concrete Composite Structure

通过10个不同连接形式和加载方式的薄壁钢-混凝土组合结构节点的试验研究,以及两个普通钢筋混凝土结构节点的对比试验,探讨了节点的工作机理、力学性能和优缺点。试验表明,所设计的不同构造形式的薄壁钢-混凝土组合结构节点均具有良好的延性性能和足够的承载能力,可以供实际设计时参考。

Through the experimental research of ten joints of thin-walled steel-concrete composite structures with different connection forms and loading modes, and two ordinary reinforced concrete joints for the contrast test, the working mechanic and the mechanical property together with the merits and faults of these joints are explored. The test indicates that the joints of the thin-walled steel-concrete composite structures have better ductility property and enough bearing capacity which can be referred in the actual project.
