- •
Flexural tests of pultruded GFRP laminates exposed to six different hygrothermal aging environments were conducted.
- •
The long-term hygrothermal aging effects on flexural properties accounting for temperature variation during exposure were predicted by combining Phillips equation and Arrhenius relationship.
- •
Predicted results were compared with design values prescribed by ACI-440, TR-55 and GB50608 design guidelines.
