Lifecycle Performance Assessment Technology for Port Steel Structures with a Focus on Post-repair Performance

摘要

Prolongation of the Service Life of Aging Port/Harbor Steel Structures In order to prolong the service life of aging port/harbor steel structures by means of rationalized maintenance, it is important to precisely gauge performance before and after repair, to assess lifecycle performance during the designed service life, and to provide appropriate inspection and maintenance. Targeting steel pipe piles with deteriorating performance due to corrosion, we have studied the post-repair load carrying capacity and durability of these piles repaired by steel plate welding. An outline of our study follows.
