Limit State of Crackwidth (Panel Discussion at the Annual Conference of Indian Road Congress, February 1980 at Jaipur)

摘要

A rational design specification for limit state of crackwidth is suggested. The various elements of the specification are discussed. The permissible crackwidth limit is recommended to be delinked from durability criterion. The Model Code formula for computing crackwidth seems to merit an axiomatic choice as the basis of design rules. Design tables for permissible stress (crackwidth limit state) are appended and their use to simplify computation is illustrated.
