Abstract

A concrete structure has to be thoroughly planned,designed,executed and maintained to keep its performance over its corresponding requirements throughout the life-cycle.However,structures suffering from serious damages in structural members have been often found due to various reasons.One of the reasons is lack of total management of the structure.The life-cycle management is an organized system to support engineeringbased decision making for ensuring performance of a structure at the design,execution,maintenance,and all related work during its life-cycle.The life-cycle management is implemented according to the life-cycle management scenario in which balance of several sustainability indicators would be considered with ensuring overall sustainability.This paper presents the concept and framework of the life-cycle management of concrete structures to ensure sustainability during the life-cycle of the structure.
