新型方钢管混凝土柱与混凝土梁的节点破坏机理
|
摘要
结合我国现行钢管混凝土柱在实际工程中的应用状况,提出了用于方钢管混凝土柱-钢筋混凝土梁框架结构的新型连接节点形式非穿心暗钢牛腿方钢管混凝土柱与混凝土梁节点,采用了X型加载试验方案,制作了1∶3的试验模型,进行了低周反复荷载作用下的试验研究,得到了相关的钢筋应力应变发展规律和相应的滞回曲线,通过对试验结果节点破坏的机理分析,提出了进一步的改进措施.试验研究结果表明,这种节点具有可靠的受力性能,与常规的连接方式相比相对简捷而可靠.
In connection with the application of concrete-filled steel tubular column in the engineering practice in this country at present,a new fashioned connection in framed structure of concrete-filled square steel tubular column with reinforced concrete beam was proposed,being a connection of concrete beam with non-through hidden steel corbel steel tubular column filled with concrete.A 1 to 3 scaled test model was made for conducting experimental investigation of low-cyclic loading of this connection with X-type loading scheme,so that the propagation pattern of the stress and strain within the relevant reinforcement and corresponding hysteresis loop were obtained.According to the experimental result,the destruction mechanism of the connection was analyzed and the measure of further improvement was proposed.It was preliminarily shown by investigation result that this kind of connection possessed reliable kinetic performance,being a relatively simple as well as a reliable connection form,compared with the conventional one.
