摘要:

在已破坏的钢管混凝土梁-柱节点试件上,截取尚未破坏的节点区域,研究带有芯钢管的钢管混凝土节点的受力机理。对节点采用不同加载方式使其破坏,从其破坏过程、破坏形态及荷载-位移曲线等方面,分析在不同加载方式下节点各组成部分的工作状态、特点及性能差异。研究结果表明:对节点全截面加载可得到节点的最大承载力,仅对芯钢管内混凝土加载可得到节点最小承载力,其最小承载力大于所连接的钢管混凝土柱的承载力,满足节点要求; 对于不同加载方式,节点的芯钢管受力状态不同,但无论何种加载方式,芯钢管、外围密排环箍主要为间接受力,起约束核心混凝土的作用。

Abstract:

The bearing mechanism of a new type joint with core steel tube was studied. The specimens were intercepted from the remnant joints area of being destroyed concrete-filled steel tubular joints specimen. The characteristic of the member of the joint was analyzed by the failure process, the main failure formation and the load and displacement curve in the different load modes. The result shows that the maximal bearing capacity was obtained by loading on the full section of the joint, and the minimal bearing could be obtained by loading on the concrete of the core steel tube. But the minimal bearing is also bigger than the bearing capacity of the CFST column; it meets the joint seismic principle. The core steel tube of the joint has different bearing states under different loading modes. The loading modes of the core steel tube and the looping take restriction effort on the core concrete indirectly.
