The mechanical properties and durabilities of fiber advanced composites make them ideal for widespread applications in construction worldwide. However, one of the problems of fiber reinforced advanced composites has expensive initial costs. So the efforts for lowering the initial cost have to be needed. There has been hardly assessment results of life cycle cost for fiber reinforced advanced composites in construction field, but some papers showed that total life cycle cost could be profitable, if the initial cost could be reduced. The purpose of this paper is to report assessment results of LCC(Life Cycle Cost) for application of FRP(Fiber Reinforced Plastic) in construction field.
