Abstract��The importance of high strain low cycle fatigue performance on aseismic design of construction steel was introduced in this paper, and the relationship between high strain low cycle fatigue and static load strength and ductility was discussed and the high strain low cycle fatigue of the low alloy and high strength H-beam was studied by using a MTS810 series fatigue testing machine. The result shows that Q345B H-beams produced in Laiwu Steel with a circulation toughness value (��a������t) of 29.8 J/cm3 after 100 cycles have a good high strain low cycle fatigue performance.
