“…The marine environment has the characteristics such as high humidity and high salinity.
Offshore buildings and structures are affected by splash erosion and damage,and durability of steel structure is subject to severe challenges and tests.The failure mechanism of high strength steel in marine corrosive environment,the reliability assessment of structural system,and surface protection technology have received extensive attention from scholars in
China and abroad.Based on the division of marine environment,the corrosion causes and damage mechanism of high strength steel,and the relationship between mechanical property degradation and corrosion,this paper discusses the influence of Cl<sup>-</sup> concentration,temperature and humidity on the mechanical properties of high strength steel in marine environment,combined with the previous simulation research on high strength steel base metal and weld joint in ocean splash zone.The relationship between corrosion cycle and mechanical properties is introduced,and finally the trend and main directions of future research are proposed.It is expected to provide a reference for the in-depth study of localized corrosion behavior of high strength steel in marine environment,the performance optimization of new connection joints and the application of safety protection technology in the future.At the same time,it will provide a strong support for the establishment of life prediction and failure assessment method for high strength steel in marine environment.…”
