Abstract

The study of the impact resistance of concrete-filled double-skin steel tube structures in the ocean environment is essential to ensuring the safety and reliability of ocean engineering structures, and it can also promote technological progress and industrial development in related fields. Thus, this review focuses on the effect of seawater corrosion on the impact performance of concrete-filled double-skin steel tube structural members. The effects of seawater corrosion on the tensile, compressive, and hysteretic properties of steel are first summarized. Secondly, the corrosion test methods currently used in most tests, such as salt spray, immersion, and artificially accelerated corrosion, are reviewed. The research progress on the impact performance of concrete-filled double-skin steel tube members, joints and corroded concrete-filled double-skin steel tube structures is then systematically summarized. Such members mainly absorb impact through overall bending deformation. The hollow ratio, boundary conditions and other factors strongly influence their impact performance. Corrosion of course weakens the impact properties. Recommendations for further study on the impact performance of seawater-corroded steel structures are provided.

混凝土填充双层钢管在海水腐蚀下的抗冲击性能：综述

研究海洋环境中混凝土填充双层钢管结构的抗冲击性能，对于确保海洋工程结构的安全性和可靠性至关重要，同时也能促进相关领域的技术进步和产业发展。因此，本综述重点讨论海水腐蚀对混凝土填充双层钢管结构构件抗冲击性能的影响。首先总结了海水腐蚀对钢材拉伸、压缩和滞后特性的影响。其次，综述了目前大多数试验中使用的腐蚀试验方法，如盐雾、浸泡和人工加速腐蚀。然后，系统总结了混凝土填充双层钢管构件、接头和腐蚀混凝土填充双层钢管结构冲击性能的研究进展。此类构件主要通过整体弯曲变形吸收冲击力。中空比、边界条件和其他因素对其冲击性能有很大影响。腐蚀当然会削弱其冲击性能。本文提出了进一步研究海水腐蚀钢结构冲击性能的建议。
