Abstract

ABSTRACT: This paper reviews the approach and methods of durability design for concrete infrastructures in main standards and codes in Asia. The state-of-the-art of durability design in China, Japan and Asian Concrete Federation (ACF) is firstly addressed, and then the design approach is introduced for the fundamental concepts, prescriptive approach and performance-based approach. Both the strength and weakness are addressed for these two approaches. Afterwards, the Chinese code GB/T 50, 476 is reviewed for its mixed approach for durability requirements, the Japanese standard SSCS is investigated for its model-based design approaches against steel corrosion, and ACF Model Code is analyzed for its deterioration indices. The limitation on the loading-induced cracks is also critically reviewed for its pertinence to durability protection. From the review, it suggested that durability standards should continue to incorporate reliable models, life-cycle elements and multi-barrier strategy to achieve better long-term performance of concrete infrastructures.
