Abstract
The design format proposed by the subcommittee for durable concrete design of JSCE Concrete Committee is expected to obtaining durable concrete structures. According to the design format, it is to be performed by making the point sum for durability indeces greater than the point for enviromental index. However, the points assigned to technologies like concrete materials or concrete and reinforcement works, for example, seem to having no rational reason. Therefore, reliability based partial safety factor design format in which points are considered to be random variables is introduced, alternatively, to investigate the usefulness of the format.
