The paper presents the method of local plastic buckling to determine the available ductility of a steel structure subjected to seismic actions. The specialized computer program DuctRot-M is developed with the aim of determining the ultimate plastic rotation. The main factors influencing the rotation

In order to establish a ductile fracture criterion, several potential fracture parameters were investigated by comparing numerical simulations of crack extension with available experimental data. Based on the comparison, a fracture criterion, the Global-Local Fracture Criterion (GLFC), was proposed.
Several approaches to addressing ductile fracture are possible . The most common one is through the use of a global approach, which phrases the fracture resistance in terms of global parameters, such as J,' and S,-(CTOD) . Unfortunately, many works [1-4] have shown that J,C and S. are the specimen-g
