新型T形头单向螺栓能够有效解决传统高强螺栓无法直接应用于钢梁-钢管柱栓接节点的问题。然而，采用此类新型螺栓连接的梁柱节点中各组件承载机理尚不明确，有待进一步探索。T形头单向螺栓连接节点的特征在于端板及钢管柱壁上具有栓孔形状。为探索此类新型连接节点中端板及钢梁组件的力学响应与承载机理，文章基于组件法，通过有限元分析软件ABAQUS对T形件节点的抗拉性能展开了系统的数值分析。主要研究内容和结论如下：建立了精确的节点三维有限元模型，研究了T形头单向螺栓连接T形件节点中翼缘出现的5种典型屈服线模式，并开展了广泛的参数分析。最后基于虚功原理及屈服线理论，给出T形头单向螺栓连接T形件节点的屈服承载力计算公式。

The novel T-head one-side bolt can effectively solve the problem that the traditional high-strength bolt cannot be directly applied to the bolted beam to tubular column joints. However， the bearing mechanism of each component in the beam-column joint with this novel bolt is still unclear and needs to be further explored. The T-head one-side bolt is characterized by the shape of the bolt hole on the endplate and tubular column. To explore the mechanical response and bearing mechanism of the endplate and beam components in this novel bolted connection， the finite element analysis software ABAQUS was used to carry out a systematic numerical analysis on the tensile performance of the T-stub connections based on the component method. The main research contents and conclusions are as follows： an accurate three-dimensional finite element model of the connection was established， and five yield line patterns on the T-stub flange in T-head one-side bolted joint was studied. Finally， the calculation formula for the yield strength of T-stub joints with T-head one-side bolts is given based on the principle of virtual work and the yield line theory.
