AB This paper presents a study on the modelling and estimation of stress concentration at thetips of leg stiffeners in ship-to-shore (STS) quay cranes, which is intensified in those on the sea-sideleg extensions, which are more prone to crack formation, notably following structural heightening ofthe cranes. A computer-simulated database was generated, incorporating mechanical parameters andgeometric features that impact stress concentration. These variables can then be integrated as inputsinto a multiple linear regression model (MLR). This methodology offers an alternative to the finiteelement method (FEM) for the computation of stress concentration and deformations. At the sametime, the statistical significance of the parameters influencing this scenario is determined, ensuring acomprehensive assessment of their impact on the studied phenomenon. The research underscores theimportance of incorporating stress concentration and structural geometry considerations into cranedesign or modification, given their crucial role in preserving the remaining lifecycle of the structure.Crack initiation is significantly intensified in regions characterised by high stress concentrations,particularly in areas where there are geometric changes at the tips of the stiffeners, where localstiffness is altered. All of this is in combination with work cycles under the supported loads.
