| 内容記述 | With the growing amount of concrete in the capital infrastructure, the maintenance and management burden is increasing and the calculation of life-cycle-cost and service lifetime are gaining in importance. The design, construction, maintenance, and management of structures raises the following questions : (1) Will the concrete structure provide service over its lifetime without reinforcement and repair? (2) How will performance and safety deteriorate if the structure is left alone? (3) How can current durability designs be checked? Accordingly, there is a need to predict the deterioration and service life of concrete structures. A method of achieving this needs to be established as soon as possible. The purpose of this study is to develop a technique for predicting and evaluating the service life of concrete structure (reinforced concrete ［RC］ structures) design in cold regions through predicting deterioration. This paper describes the development of a technique and a case-study in which the technique is applied to a tentative model. The case-study results show that the water-cement ratio and depth of cover over reinforcing steel influenced deterioration over time due to neutralization and steel corrosion. Between some cases of choosing of the rate, several-fold variations in neutralization depth and a factor of two in the time until the onset of steel corrosion were recognized. As shown in Fig. 4, it was determined that the difference in synthetic degree of deterioration was 20％ at 50 years after construction. | |||||
