Analytical Study on the Effect of Corrosion to the Construction Performance
Journal Title: Natural and Engineering Sciences - Year 2019, Vol 4, Issue 1
Abstract
Corrosion is one of the most important factor to achieve in completing the service life of reinforced concrete structures also cause significant losses in energy damping capacities of structures. In this study, the reinforced concrete column designed in ½ geometrical scale was subjected to accelerated corrosion test for 26.5 days under 1 ampere constant current. As a result of the experiment, weight loss and strength reductions was obtained. Loss of strength in reinforcement due to corrosion damage was obtained with experimental procedure. Loss of cross section and reduction of compressive strength of concrete were obtained with empirical formulas in the literature. Thanks to this data, 3 different scenarios applied on a sample building in Hatay province. Static pushover analyzes of the sample building designed in accordance with the regulations were carried out with Sap 2000 program under the specified corrosion scenarios. The load-displacement curves obtained by the scenarios are compared with the curves of the reference building. As a result of the comparisons, it was observed that corrosion damage caused significant loss in horizontal load carrying capacity of the building. The corrosion scenarios show that corrosion in columns or beams changes collapse modes of the structure.
