The strength properties of structural epoxy adhesives at elevated temperatures is experimentally determined. Finite element analysis of thermal gradients in typical columns is provided. Both the ASTM E-119 and the SDHI time-temperature fire exposure curves are considered in evaluating the fire ratings of epoxy repaired concrete components. The relationship between strength, duration of fire exposure, and type of fire exposure is provided in both graphical and tabular form.
