Application to Post-buckling Ductile Fracture of Steel Stub Columns
Abstract In practice, ductile fracture after occurrence of local buckling has been observed in actual steel members during strong earthquakes, such as the 1995 Kobe earthquake. This chapter aims to establish a simulation method for the post-buckling cracking process on the basis of formerly proposed cyclic fracture and plasticity models. Experimental tests on twelve heat-treated square hollow section stub columns are carried out under different cyclic loading histories. Numerical simulation of the post-buckling ductile cracking of the specimens is conducted, where the simulation results indicate that the crack initiation of the specimens can be evaluated with a favorable accuracy, while further study is required for the crack propagation under ultra-low-cycle fatigue loading.
