Parametric Study of Hysteretic Behaviour of Combined Welded Heavy Steel Plates with Accumulative Damage
The accumulative damage model in which the material’s plastic strain is defined as variable and the energy dissipation is also considered is applied to the combined welded heavy steel plates. And the reliability of the model is confirmed by comparing the computed results in finite element project ABAQUS to tested results from previous researcher. On that basis, a series of steel plate components are computed to analyze their hysteretic curves and ductility factors. The influences of steel plate thickness, web’s height-thickness ratio and flange’s width-thickness ratio on hysteretic behavior are studied.
