Abstract: The division of the ambient environment effects of concrete structures home and abroad are com- pared, then the crack limit values based on durability are analyzed , the factors considered in each standard are pointed out, and then control measures of non-ｌｏａｄ cracks are summarized. the differences and similarities between standards are given , so that the engineering staffs can understand and apply the design specification flexibly.

Keywords: Concrete structure; Durability; Crack limit values; Control measures
