摘要

•Welding residual stress has a significant detrimental impact on the strength of stiffened plated structures.•Data-driven model is proposed for estimating the ultimate compressive strength reduction of stiffened panels caused by welding residual stress.•Results obtained in interpolation and extrapolation scenarios prove the high accuracy and reliability of the proposed method.
