| Abstract | Nowadays, many reinforced concrete structures were constructed, and these structures have been used for several years. Thus, a lot of structures need to be repaired or maintained in timely manner. With this reason, predicting the remaining service life of reinforced concrete structure is vital for repairing and maintenance work. Nevertheless, the predicting of remaining service life is somehow complicated since the reinforced concrete structure can be deteriorated by many factors, for example, the corrosion of reinforcing steel, which is one of the major problems that might affect to the capacity of structure. From the previous work, the effects of the corrosion, which impact on capacity of the structure, might consist of reduction of steel section area, un-bonding effect and mechanic of corroded steel reinforcement. Therefore, this research will study on the effects of the corrosion that will impact on the capacity of the structure by focusing the moment capacity of the beam structure, and the experiment will set up for the purpose of finding the effects, which can reduce the capacity of the structure in order to predict the moment capacity of structure. The results show that predicting the moment capacity of the corroded beam that has few weight loss percentage on tensile steel can be simplified by using ACI 318M-08. In contrast, the corroded beam that has great weight loss percentage on tensile steel, the un-bonding effect shall be concerned in the calculation. And the pitting effect can be the major effect that reduces the capacity of the structure. |
