Authors' response

摘要

The authors would like to express gratitude to William Gamble for his interest and valuable feedback on "Modeling the Resistance of Precast, Prestressed Concrete Hollow-Core Slabs Exposed to Fire." The discrepancy in the paper regarding the limiting temperature on the unexposed surface is due to inconsistency in the conversion of temperature on Celsius and Fahrenheit scales (Δ℃ →Δ℉). However, the authors are aware of the fact that the critical temperature rise for the unexposed side of the slabs is 250 ℉ (139 ℃) for the average temperature and 325 ℉ (181 ℃) for tem- perature at a single point, as per ASTM-E119. Thus, temperature limits of 159 ℃ for average temperature and 201 ℃ for single-point temperature were applied in evaluating failure (fire resistance) of the slabs. It should be noted that this error does not change or affect the results presented in the paper.
