Abstract:Rust is a major problem in steel bridge construction because it has the potential to affect the integrity of the structure and is also an important consideration for inspection and maintenance programs. This study shows the results of laboratory tests on the effect of rust within 1 to 9 weeks on fracture toughness as one of the important mechanical properties of steel bridge elements. The specimens in this study were made of SM 490 type, steel commonly used for bridge construction. Rustless and rusted specimen… Show more
