Concrete and steel has been used as the main material of structure from building and drainage pipe. However, many problems such as corrosion and rupture had occurred in the Water Supply and the Sewer System. Additionally, the government has invested big budget to Deteriorated pipe replacement and maintenance. Replacement of existing pipelines in order to solve these problems, GFRP pipe(glass fiber composite material pipes) is aspiring to replace the tube. GFRP has high strength, restore performance, durable and lightweight properties. However, high strength GFRP pipe is weak in buckling problem. This study is to analysis Optimization Design models for resisting bucking problem of GFRP pipes. Thus, various tests Changed the angle of Glass-Fiber-Reinforced Layer and the resin content of resin-mortar were performed for GFRP pipes to estimate material characteristics of GFRP in this study. Buckling analysis of composite structures under external uniform pressure was performed with the results obtained through test.
