2 Identify if the following statements are True or False 10

2. Identify if the following statements are True or False (10 Points) (à) FRP composites will replace structural steel and steel reinforcing bars in Civil Engineering industry due to non-corrosiveness and high strength. (b) Transverse strength and transverse modulus of a composite is fiber dominated. (c) CFRP internal reinforcing bars can be combined with steel reinforcing bars in concrete because carbon fibers are stable in alkaline concrete environment. (d) FRP internal reinforcement is ineffective in compression members. (e) It is preferable to fabricate shear reinforcement (stirrups) with thermoplastics for use as ties in beams and columns so that the reinforcement can be heated to alter the shape of the stirrups as required. (1 Glass is stronger in its fiber form than its bulk form because of reorientation of the links along the longitudinal axis of the fiber.
