that under static loading and is difficult to be recorded completely
during the tests.
This paper aims at the experimental and numerical analysis of
the dynamic behavior of tubular T-joint under impact loading. A
finite element model is developed and is validated by the impact
tests conducted by the authors. Numerical analysis of the failure
mechanism of steel tubular T-joints under impact loading is also
conducted. The local indentation of the chord is distinguished from
the global deformations of the T-joints through an equal area axis
method and the yield line theory. Finally, an equivalent impact
force estimation method is proposed to determine the anti-impact
resistance of steel tubular T-joint.
