抄録
内容記述 In order to keep the good performance and elongate the service life of the structure members at the least cost, it is necessary to find out the deterioration characteristics, decide the lifespan and choose the appropriate maintenance methods. Usually outdoor exposure tests are performed to solve these problems, however, the outdoor exposure tests need enormous time and effort. In this study, a series of accelerated exposure tests, which can be controlled in limited time and with little cost, are performed in the laboratory to investigate the environment impact on the uncoated steel plates and the rubber bearings. An accelerated cyclic corrosion-environment named S6-cycle is employed on the uncoated steel plates. For rubber materials, six kinds of accelerated exposure tests including the thermal oxidation, ultraviolet radiation, ozone, low-temperature ozone, salt water and acid rain mist combined cyclic tests, are carried out to simulate different degradation factors. The time histories of the specimen performances are examined. Compared with the results from the outdoor exposure tests as well as the investigation of the amount of flying salt, the acceleration coefficient of the uncoated steel plates is calculated. Through the six accelerated exposure tests the predominant degradation factor affecting the rubber materials is clarified. The long-term behaviors can be predicted using the Arrhenius theory, and a modified method is proposed to take the location and the temperature fluctuation into consideration. In this study, the application of the accelerated exposure tests to simulate the atmospheric environment is presented.
