摘要
根据方钢管混凝土柱外置式环梁节点的受力特点 ,设计了联结面试件 ,进行了八个联结面试件的抗剪试验 ,变化参数为混凝土强度、加载剪跨比、肋钢筋的布置方式及肋钢筋的直径 .分析了试验现象及试件中钢筋应变发展规律 .试验结果表明 ,这种联结面传力方式可用于工程实践 .并提出了面向工程的联结面设计方法 .
According to the characteristics of the ring-beam connection located outside concrete-filled rectangular steel tubular(CFRT) columns,the interface specimens were designed and the shear-resistant tests on eight specimens were carried out.The main parameters varied for the tests are the concrete grade,the shear-span ratio,the location and the diameter of the rib-bar welded on the columns.The shear behavior of the specimens and the influence of different reinforcement of the connections were investigated.The strain on the reinforcing bars in the specimens was also analyzed.The test and analysis have showed that the shear-resistant capacity of this new type of connection is good enough when used in practical engineering.
