With the acceleration of the economic development, people has more and more demand on reinforced concrete, a kind of building materials, whose properties directly affect the security and reliability of architectural entities. However, reinforced concrete that has long been submerged in the marine environment not only has to bear various loads such as wind and rain, but also suffer from physical and chemical corrosion, which in turn worsens its durability, degrades its mechanical properties, and badly destroys practical properties of marine works. To accurately evaluate how the aseismic behavior of reinforced concrete frame structures in the marine environment is subjected to change with chemical attack, this paper adopts the ABAQUS, a finite element software, to simulate and compare aseismic behaviors of an immersed tunnel structure newly built and after withstanding 60 years of chemical corrosion in the marine environment. The findings show that chemical corrosion in the marine will greatly degrade the aseismic behavior of reinforced concrete structures, providing a theoretical basis for qualitative evaluation on the impact of chemical corrosion on aseismic property of reinforced concrete frame structures.
