内容記述 | In order to investigate crack occurrence condition of natural rubber bearings of bridges, a series of accelerated exposure experiments applying the environmental degradation factors (temperature and ozone) and external loads on the rubber bearing specimen was carried out. The condition of ozone-induced crack occurrence was identified. That is, cracks occurred in the regions with local tensile strain on the surface of rubber bearing by 40 degrees Celsius of temperature and 100 pphm of ozone density. Furthermore, the cracks were repaired by coating with polyethylene material. The repaired cracks were not extended under the same experimental condition. The load carrying capacities of the virgin rubber bearing, the bearing with cracks and the repaired bearing were almost the same because the cracks were generated only in the surface rubber cover of specimen. | |||||
