Abstract:
Glass fiber-reinforced polymer (GFRP) bars are allowed for use in members subjected to pure axial loads or the combination of axial compression and flexural load. However, there is a disparity in statements across different design codes and guide specifications concerning the contribution of GFRP bars to the capacity of these members.
