The T-stub is one of the most important structural components in steel frames, since its behaviour affects the behaviour and stability of the entire structure. The present study is devoted to the analytical investigation of the behaviour of this component and mainly of the bending that occurs on the bolts due to the T stub flange deformability. Moreover, the influence on its ultimate strength is studied. In addition, the problem is also examined by utilizing a finite element procedure with a three dimensional model of a simple T-stub. The model includes geometrical and material nonlinearities. The results of the finite element analysis indicate that the theoretical approach related to occurring bending on the bolts is real and some times controls the reduced strength of this component.

T型短管的柔韧性对其强度的影响

T型桩是钢框架中最重要的结构部件之一，因为它的行为会影响整个结构的行为和稳定性。本研究致力于对该部件的性能进行分析研究，并且主要是对由于T短管法兰变形而在螺栓上发生的弯曲进行分析。此外，研究了其极限强度的影响。此外，还通过使用有限元程序和简单T形桩的三维模型来研究该问题。该模型包括几何和材料非线性。有限元分析的结果表明，与螺栓上发生弯曲有关的理论方法是真实的，并且有时控制该部件的强度降低。
