Abstract
Recently, the composite material becomes more popular and its usage is kept expanding from aerospace to civil structures such as bridge decks and irrigation and drainage pipes. The major cause for the popularity can be found in its high strength, light, and excellent anticorrosive properties. Nevertheless the methods to accurately predict and analyze its structural behavior are extremely limited. This has been the major reason circumventing more prevalent use of the composite materials in civil structures. This study is a pre-study to develop the analyzing models for accurate prediction of the composite material structures. Thus, various tests were performed for GFRP pipes to estimate material characteristics of GFRP in this study. And stress-strain relation of GFRP was suggested as a bilinear relation.
