方钢管混凝土柱十字型节点力学性能试验研究
|
摘要
结合现行钢管混凝土柱在实际工程应用状况,提出了用于方钢管混凝土结构柱钢筋混凝土梁框架结构的新型连接节点形式,采用了X型加载试验方案,制做了1∶3十字型的试验模型,进行了低周反复荷载作用下的试验研究,得到了相关的钢筋和钢牛腿应力应变发展规律和相应的滞回曲线,对试验结果进行了节点破坏的机理分析,提出了进一步的改进措施,使其具有可靠的受力性能,与常规的连接方式相比是一种相对简捷而可靠的连接方式.
A new type of joint connections between rectangular concrete-filled tubular column and reinforced concrete beam was proposed.One specimen with 1∶3 scale of modeling for the practical project has been tested.The test setup of X-shape has been adopted to realize the cyclic load.The experimental phenomena and the strain distribution on different parts of the specimen were obtained from the test.In addition,the hysteresis curve of joints between the column and the beam under cyclic loads was plotted and the anti-seismic performance of joints has been discussed.The preliminary experimental results indicate that this kind of joint connection has a reliable performance and it is easy to construct.
