CARBON STEEL H BEAM SN490A has obvious merits such as good ductility, seismic behavior and hysteretic behavior. But cumulative damage caused by cyclic loading makes the ductility weakened. Bauschinger effect and cyclic hardening appear in the experiment. The details on the SEM photo shows the fracture is ductile fracture. The constitutive behavior of SN490B steel under monotonic loading and cyclic loading are different, so it is not accurate to predict the behavior of SN490B steel under cyclic loading using constitutive relation under monotonic loading.
