This paper reports on the impact of various environmental conditions on flexural response of concrete beams strengthened by mild steel and carbon fiber reinforced plastic (CFRP) plates. 80+ beams were tested under 4 different environmental conditions. Two testing ages were adopted to study the effect of exposure time. Based on experimental results, it was found that strengthened beams subjected to elevated temperatures (heating/cooling cycle) show improvement in the loading response, while use of the water immersion method causes a reduction in flexural capacity. Prolonged exposure of plated concrete beams to water conditions lead to further decreases in flexural strength. CFRP plated beams were found to show greater enhancement than steel plated beams under all conditions.
