Durability Analysis of Reinforced Concrete Structures of CTW130 Railway Network Project

The durability analyses were performed for the precast box girders, buried or lying on the soil reinforced structures and piles within CTW130 project. Within the scope of this work, concrete recipes to be used in construction and chlorite ion, temperature, distance from sea or interaction with the sea, ground chemical parameters were modeled via Life-365 ™ software. According to this modeling, the chlorite diffusion rates of the structures and the periods in which the reinforcements have lost their service life were calculated. Concrete mixtures, additives and reinforcement type selections had been made in order to provide a service life of at least 100 years. A report containing these analyzes and recommendations was prepared.
