Abstract
Corrosion of structural members of ships is one of the main problems for ship safety.
In this report effect of grooving on static strength of corroded fillet welded joints for ship structure is investigated with experimental result and FEM analysis. Four points bending test was conducted with half size model specimen of hold frame of Cape-size bulk carrier.
It is mainly obtained that in case of grooving in compressive stress region applied by bending moment, at fillet welded joint, maximum load occurs at lateral deflection of web plate and grooving width and grooving depth effects maximum load. When the size of compressive stress region is small at grooving part of fillet welded joint effect of grooving on static strength is not observed.
