meric resin, also known as fiber-reinforced polymer (FRP), are an alternative to steel reinforcement for concrete struc-tures. Fiber-reinforced polymer reinforcing materials are made of continuous aramid fiber (AFRP), carbon fiber (CFRP), or glass fiber (GFRP) embedded in a resin matrix. Examples of FRP reinforcing bars are shown in Fig. 1.1.

Experimental Study on Compression Behavior of Fiber

Fiber-reinforced resin-based composite stiffened panels are put in the hygrothermal box at 70°C and 85% RH until moisture absorption reaches balance. Then, the compression experiments on the common stiffened panels and the stiffened panels after moisture absorption are conducted to get buckling and failure loads. Test results are compared to analyze the effect of damage on the carrying
