Flexural Behavior of Concrete Beams Reinforced with Glass Fiber - Reinforced Polymer (GFRP) Bars

摘要

Concrete members reinforced with glass fiber - reinforced polymer (GFRP) bars exhibit large deflections and crack widths compared with concrete members reinforced with steel. This is due to the low modulus of elasticity of GFRP. Current design methods for predict - ing deflections at service load and crack widths developed for con - crete structures reinforced with steel may not be used for concrete structures reinforced with GFRP.
