Tests were conducted to study changes in elements during heating, to determine modulus of elasticity and ultimate strength before and after heating, and to determine losses of prestressing force by heating; tables and graphs show results; modulus of elasticity decreases by heating but is restored to certain degree by cooling; calculation of loss of prestress due to heating; strength of pretensioned columns was greater after heating.
