In this study, the property of crack growth in structural steel is investigated according to length and angle of crack at the analysis result of model. Strain energy, deformation and stress obtained by finite element analysis are compared with various configuration of crack. Stress intensity factors as fracture toughness are calculated by the basis of strain energy, deformation and stress. As there are almost no errors by comparing stress intensity factors with those from the standard formula, these calculated factors can be confirmed in order to be applied at real structure. In case cracks or holes at structure are existed, the fatigue damage possibility can be examined by use of this study result.
