| Japan faces the serious problem of increased maintenance costs from bloc obsolescence of bridges、 at a time of shrinking public works budgets. We face a demand for cost reduction and improved durability of infrastructure. The fiberreinforced plastic (FRP) is highly durable、 but its construction as reinforcement costs more than that for steel. To examine the cost performance of FRP on a concrete bridge (span length: 18 m) exposed to a chloride environment、 we[*]compared four cases in terms of the life-cycle cost (LCC) and initial construction cost. The some applications of FRP in Japan are shown in this paper. |
