The necessity of assessing the durability of structures such as bridges, offshore structures, has arisen recently. It is obvious that the maintenance of infrastructures has become a key issue to assure the desired performance in operational condition and to prolong the life of structures. As for the life cycle performance of the steel structure in the marine atmosphere, in particular, the damage due to corrosion is important rather than that by fatigue. Investigated herein is the guideline for the thickness measurement of steel elements that are subjected to the corrosion exposure at the specific inspection. Firstly, the measurement of the surface profile of strips cut from corroded steel pipes is made. Secondly, the tensile test is carried out in order to assess the effective thickness in the critical section for the mechanical property evaluation. It is shown that the precise surface profile measurement such as the interval of about 0.3 mm is necessary to evaluate the strength in tension.
