摘要
提出了一种新型的圆钢管混凝土穿心节点,并介绍了该种节点在低周反复荷载作用下的试验结果,用AN-SYS软件建模进行有限元分析。试验结果与有限元计算相对比,二者吻合良好。试验结果表明:这种新型穿心节点承载力高、抗震性好、构造简单、受力明确,有广泛的工程应用前景。
Test results of a new type of concrete-filled circular steel tubular column with piercing reinf orcing bar joints under reversed loads are presented.A finite ele ment study on the joints was made by using ANSYS. To verify the accuracy of the analytical models, results were compared to the previous test data. The calc ulated values agree well with the experimental results. The test result shows th at new type of joins have adequate bearing capacity, excellent seismic beha vior, simple type of structure ,stra...
