Recently, glass fiber reinforced polymer plastic (GFRP) pipes are increasing trend in using in the water-supply system because of their advantages such as light-weight, corrosion resistance, etc. GFRP pipes discussed in this paper have polymer mortar layer between filament winding glass fiber reinforced polymer plastic layers. So, GFRP pipe properties such as pipe stiffness (PS) and equivalent modulus of elasticity (Eeq ) for the design are complicated to predict or to measure. In this study, we proposed the equation that can predict the equivalent pipe stiffness factor (EI) in relation to PS and Eeq using thickness of each material layer. The predicted result obtained by the equation proposed in this paper is compared with experimental result. As a result, it was in the range of –5% to +2%. Therefore, it is found that the proposed equation can be used to design GFRP pipe used in practice.
