主管壁加厚方钢管T型节点滞回性能研究OA北大核心CSCDCSTPCD
Study on hysteretic behavior of square tubular T-joints with increased chord thickness
为了研究主管壁局部加厚对方钢管T型节点滞回性能的影响,对一个主管壁局部加厚的方钢管T型节点试件和一个主管壁未加厚的方钢管T型节点试件进行试验测试和有限元模拟.试验中,通过控制支管的竖向位移对方钢管T型节点试件施加低周往复循环荷载,研究试件的变形和破坏模式,并进行相关抗震性能指标(延性系数和能量耗散)分析.试验结果表明:主管壁局部加厚能够明显改善节点的滞回性能,同时能够使节点由带有明显延性特征的断裂破坏转变为主管壁厚改变处的延性屈服破坏.利用有限元…查看全部>>
In order to study the hysteretic performance of square tubular T-joints with increased chord thickness, experiments and numerical simulation were carried out on a full-scale square tubular T-joint with normal chord thickness and one with thickened chord.Low-cycle loading was applied to the specimens using displacement control method.The deformation and the failure mode were studied.The corresponding indices of seismic behavior, such as the ductility ratio an…查看全部>>
