초록

In the water supply pipeline system, pipes made by cast iron, PE, PVC are generally used. However, the structural performance of these materials can be declined when used for long periodsof time because of corrosion, creep, deterioration of the material, etc. while glass fiber reinforced polymer plastics (GFRP) have many advantages such as light-weight, corrosion resistance, smooth surface, etc. For these reasons, GFRP pipes are good for construction when it is buried underground and are increasing trend in applying the water supply pipeline system. Therefore, more optimized structural design methodology should be developed. In this paper, we confirm pipe stiffness (PS) of GFRP pipe in which the pipe stiffness indicates the load-bearing performance. We compared data of parallel-plate loading test and theoretically predicted PS by the classical elasticity theory and the finite element method (FEM).
