Modelling of Damage Progression and its Effects on the Expected Safety and Satisfactory Performance of Existing Reinforced Concrete Infrastructure

点击翻译按钮获取中文摘要

The extent of reinforcement corrosion in existing infrastructure will influence demolish/repair decisions, maintenance strategies and hence the frequency, timing, extent and required level of efficiency and effectiveness of repairs. The project will provide improved evaluation of existing structural systems by considering improved deterioration modelling and predictions of safety and satisfactory performance. The potential economic benefits of greater precision in infrastructure replacement or repair strategies and of the risks involved are large given that the size of Australia's infrastructure stock is valued at over $400 billion and its maintenance involves considerable costs.
