Abstract

The American Concrete Institute (ACI) currently has an approved design guideline for FRP-reinforced concrete: ACI 440.1R-15 Guide for the Design and Construction of Structural Concrete Reinforced with FRP Bars. Work is now in progress to develop a consensus-based standard design code for GFRP-reinforced concrete dependent to ACI's 318-14 Standard Building Code for Structural Concrete. The GFRP code language will generally follow the principles recommended in the ACI 440.1R-15 guide, with a number of significant changes that have resulted from recent research and the need to develop provisions in areas that the ACI 440.1R-15 guide does not address. Prior to approval by ACI, the proposed changes must be vetted in practical design situations. Accordingly, design examples consistent with the ACI draft code language have been developed and their solutions examined to study the impact that proposed code language may have on the design of GFRP-reinforced concrete members. This paper discusses one of those design examples to: (1) promote understanding and provide evidence that draft code provisions can be practically implemented in typical design situations; and (2) identify situations in which draft code language may require modification.
