Cold Climate Effects on Concrete Bridge Performance

Abstract Concrete bridges in cold regions face critical durability and safety challenges. Factors such as corrosion from de‐icing salts, freeze‐thaw cycles, and hydraulic pressures from ice loads put these structures at higher risk for deterioration and failure. Understanding the primary failure mechanisms—corrosion, freeze‐thaw damage, and hydraulic impacts on substructures—is essential for maintaining safe and functional infrastructure in these climates. This study addresses these mechanisms, examining also how climate change may further exacerbate their effects. Gathering information from existing investigations and studies from different countries, this paper examines common vulnerabilities and failure modes in concrete bridges in cold regions, presenting potential solutions and preventive strategies to enhance their resilience. The paper also discusses potential preventive measures to reduce the impact of cold‐related degradation and climate change in concrete bridges.
