- Remaining Structural Performance of Steel Pipes Corroded in Marine Environment
抄録
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 elements in the marine atmosphere, in particular, the damage due to corrosion is important rather than that by fatigue. Investigated herein is the strength and ductility of steel pipes that were subjected to the corrosion exposure in the field under severer marine environment for about 20 years. Firstly, the measurement of the surface profile of corroded steel pipes is made. Secondly, FE Analysis is carried out in order to obtain the relation between the applied axial compressive loads and the axial shortening of the corroded specimens. Then the evaluation method for remaining structural performance of corroded steel elements is discussed.
