Abstract:

This paper analyzes the GFRP- reinforced concrete beam under combination of compression force and bending moment by establishing an interaction diagram following steel-reinforced concrete practice. The results show that as the compression force increases, the bending moment capacity gets larger. Therefore, the moment capacity is bigger than that designed per ACI 440. 1R, where pure bending is the only parameter considered ignoring the influence of compression force. By building the interaction diagram, different combinations of demand compression and flexure forces could be testified to see if the reinforced section’s strength is enough. By comparing concrete sections with different GFRP reinforce ratio, it is found that the influence of reinforcement ratio becomes smaller on the section’s capacity as the ratio gets bigger. In addition, for a section under large bending moment and small compression force, increasing the GFRP reinforcement will increase the section capacity effectively. However, when the section is under high compression force and bending moment, decreasing the concrete cover works more efficiently than increasing the reinforcement ratio. Therefore, different combinations of demand forces need to be investigated case to case to determine the most efficient way to design GFRP- reinforced concrete beam safely and economically.
