In view that some ships can’t berth due to the deviation of dimensions ,we propose a scheme,i.e.sticking angle bars on the original concrete members toextend the original member 1 meter downwards and strengthen its cantilever end as well.Berthing force review and finite element calculation show that the berthing members can meet the requirement of berthing after the renovation.The construction and engineering review also indicates that three years’ port operation is normal and the main steel structure is complete.This case of renovation and strengthening of berthing members may serve as reference for similar projects.
