摘要：

Ever increasing attention is being paid to deterioration prediction and service life modelling of reinforced concrete structures. Research has progressed to a stage where service life models and design philosophies are, to varying degrees, included in some codes and standards, such as the fib Model Codes and ISO 13823. This has helped to base practical durability design on sound engineering approaches. This paper reviews service life modelling and prediction, and service life design, covering limit state design philosophies and deterioration models. An overview on recent developments, and a critical review on common assumptions in service life modelling and on the application and limitations of the various approaches, are presented. It is emphasised that design approaches and models need to be validated with field observations. It is argued that a performance-based approach is the most suitable engineering tool for durability design.
