However, its coefficient of thermal expansion is different from that of concrete. This difference raises concerns about the potential for concrete cracking during the hydration process. To address this concern, a thermal-structural finite element model was developed to predict the stresses in SS reinforced concrete (RC) sections during the hydration process. Different curing regimes were taken into consideration. The analysis was performed in two stages. First, a transient thermal analysis was performed to determine the temperature distribution within the concrete section as a function of concrete age and its thermal properties. The evaluated temperature distribution was then utilized to conduct stress analysis. The ability of the model to predict the stresses induced by the expansion of the bars relative to the surrounding concrete was validated using relevant studies by others. The model outcomes provided in-depth understanding of the heat of hydration induced-stresses in the examined SS RC sections. Another concern for SS RC sections relates to the undefined yield point for SS. This creates uncertainty while calculating the moment of resistance of a SS RC section.

The experimental phase involved testing four beams and four columns. Both austenitic (316 LN) and duplex (2205) were considered.
