Considerations for Life-Cycle of Concrete Structures
A concrete structure has to be adequately planned, designed, executed and maintained to keep its structural performance over its requirements throughout the life-cycle.However, structures suffering from serious deterioration in structural members and sometimes subsequent loss in performance have been often found due to various reasons.One of the reasons is lack of total management for the structure.To meet these facts, it is extremely important to pursue coordination of engineering work in the stages of design, execution and maintenance.The life-cycle management is an organized system to support engineering-based decision making for ensuring sufficient structural performance and long life of a structure at the design, execution, maintenance, and all related work during its life-cycle as shown in Figure 1.The life-cycle management is implemented according to the life-cycle management scenario in which balance of several sustainability indicators should be considered with ensuring performance requirements.The sustainability indicators will be determined from the social, environmental and economic points of view.The scenario should be regularly reviewed based on the PDCA cycle and be updated if necessary.This paper deals with the concept and framework of the life-cycle management for concrete structures to ensure structural performance and sustainability during the life-cycle of the structure.
