- Abstract
- In this study, a development of the rust formation was modelled to quantify the structural impact in steel reinforced concrete. The interfacial gap, cover depth and diameter of steel rebar were taken for variables in modelling. It was found that the interfacial gap was the most influencing on the structural limit at steel corrosion, followed by steel diameter and cover depth. At 75 mm of cover depth with 20 mm of the steel diameter, the rust amount to reach yielding accounted for 2.66–11.58 µm to 1–10 µm of the interfacial gap, while 16.95–27.69 µm to the equivalent rust formation. © 2022 Elsevier Ltd
