Considerable research has been conducted in recent years into the reliability of reinforced concrete structures subjected to time dependent changes in resistance and loading. The use of braided Fiber Reinforced Polymer (FRP) rebar offers potential performance benefits as they are not subjected to the corrosion issues that frequently add uncertainty to reliability calculations. However the structural safety associated with this composite material is still not fully understood. FRP is an inherently brittle material, a feature that fundamentally changes the approach required in assessing reliability of structures manufactured using FRP rebar. TRUSS will propose models that will allow reducing the uncertainty associated to the response of Braided FRP. Experimental testing programmes at UCD (scanning electron microscopy and X-ray Photoelecton Spectroscopy, etc.) planned in collaboration with Burgmann Packings will be utilised by the ESR to develop reliability models that will determine structural safety.
