Abstract :
This paper presents that a life span on serviceability and safety is obtained from questionnaire survey using Analytical Hierarchy Process (AHP) method. A concrete bridge and landing pier are selected as target structures. Questionnaire is carried our against experts of 12 persons who have an experience for 10 year and engaged in design, research of concrete as experts of durability in University, administration and contractor. According to analysis, the life span on serviceability is obtained as T=36 year for concrete bridge and T=31 year for landing pier respectively. The life span on safety is obtained as T=49 year for concrete bridge and T=41 year for landing pier respectively. Life span of landing pier is a little bit of shorter than concrete bridge
