This thesis presents the results of an experimental investigation into the behaviorof a pultruded E-glass-polyester fiber reinforced polymer FRP composite undersustained loads at elevated temperatures in the range of those that might be seen inservice. This investigation involved compression creep tests of material couponsperformed at a constant stress level of 33% of ultimate strength and three temperatureslevels; 23.3°C 74°F, 37.7°F 100°F, and 54.4°C 130°F. The results of theseexperiments were used in conjunction with the Findley power law and the Time-Temperature Superposition Principle TTSP to formulate a predictive curve for the longtermcreep behavior of these pultruded sections. Further experiments were performed toinvestigate the effects of thermal cycles in order to better simulate service conditions.
