为研究装配式钢框架钢管内套筒‐T型件梁柱连接节点力学性能，通过改变内套筒厚度对节点进行有限元分析，对其极限承载力、荷载‐位移滞回性能、耗能能力、破坏形态等进行深入研究。结果表明：增大内套筒厚度，可以提高节点极限承载力和耗能能力，当内套筒厚度大于柱壁厚度2 mm时，节点表现出良好的滞回性能；当内套筒厚度取值过大时，节点力学性能提升不明显；位移加载过程中，高强度对拉螺栓预拉力施加面的拉力值随内套筒厚度增大变化不明显。

In order to study the mechanical properties of prefabricated steel frame inner sleeve‐T section beam‐column joint ,finite element analysis of the nodes was carried out through changing the thickness of inner sleeve . Bearing capacity ,hysteretic behavior ,energy dissipation capacity and failure modes of nodes were analyzed deeply . The results showed that increasing the thickness of inner sleeve can improve the bearing capacity and energy dissipation capacity of the node ,and the node exhibited good hysteretic behavior when the thickness of inner sleeve was more than cylindrical wall two millimeters .When the thickness value of inner sleeve was high ,the changes of mechanical properties of the node were not obvious .In the process of displacement loading ,the changes of tensile force values of pretension applied surface with increasing the thickness of inner sleeve in the high strength split bolts was not obvious .
