Investigation on Life Cycle Cost Analysis of Structures Based on Improved Life-365™ Model

This paper proposes an improved Life-365™ model, which is used to life cycle cost analysis. The main content as follows: (1) existing model was based on artificial neural networks, and the predicted results of were in good agreement with experimental data. (2) Adding fibres concrete can improve durability structure, but unable reduce structure. (3) use BFRP reinforcement instead steel improves initial construction costs reduces later maintenance costs. When 100-year design reached, a reinforced fibre structure 40.61% lower than that
