Abstract
One of most importances to enhance durability of concrete structures is design details which strictly governs an easiness of concreting works such as pouring and compacting fresh concrete, as a result, which determines quality and performance of durability of structures. From this point of view factors on design detail have been discussed verifying by some experimental works focused on water penetration at the surface layer of members and a new format for design drawings concerned with concrete cover is proposed. Authors are certain that this paper could assist a spread of Proposed Recommendation on Durability Design for Concrete Structures published by JSCE Concrete Committee.
