This chapter presents the state of the art of the durability requirements in design codes and standards. First, the durability requirements are reviewed for EuroCode (EN206‐1, EN1992‐1‐1), ACI‐318, JSCE code, and China codes (CCES01, GB/T50476), including both the design framework and material requirements. Then the chapter focuses on the GB/T50476 code for durability design of concrete structures. The durability design basis is constituted through the environmental classification, the prescription of design service lives and the durability limit states, together with a global framework for durability requirements on material and structural levels. Afterwards, the action intensity is refined for each environment class and the detailed requirements are elaborated with respect to the action intensity and expected design life. As a particular case, post‐tensioned prestressed structures are treated and multi‐barrier protection strategies are recommended for post‐tensioned tendons and anchorages exposed to different environmental actions.
