环口板加固T型圆钢管节点受压承载力与滞回性能的试验研究

Experimental Study on Compression Bearing Capacity and Hysteretic Behavior of T Circular Steel Tube Joints Strengthened by Annular Plate

为了研究环口板加固对T型圆钢管节点的受压承载力与滞回性能的影响,制作了两组试件,每组试件分别有一个未加固T型和一个环口板加固型T型圆钢节点。第一组试件与第二组试件分别进行受压承载力试验与滞回试验。实验结果表明环口板加固节点的承载力与滞回性能分别好于未加固试件。

In order to study the influence of bearing capacity and hysteretic behavior of ring plate reinforcement on the compression bearing capacity and hysteretic behavior of T type steel tubular joints, to making the two groups of specimens, specimens in each group often have a unreinforced T type and a ring plate reinforced T type circular steel tube joint. Both groups are all taking a compression bearing capacity test and hysteresis test. The experimental results show that the bearing capacity and hysteretic performance of the collar plate reinforced joints are respectively better than that of the unreinforced.
