In order to study extremely low cycle fatigue performance of structural steel and find a suitable constitutive relationship under cyclic loading, a total of fifty Q235B and Q345B steel extremely low cycle fatigue experiments have been carried out. The mechanical behavior of Q235B and Q345B structura...
