Estimation of the Required Fire Resistance Time Using a Fire Characteristics Graph

In actual fires, the nature of fires varies from compartment to compartment. However, domestic standard utilizes a uniform fire resistance 60 min. Therefore, in this study, required time was calculated by predicting temperature check whether standards are safe. The results show that, even if facilities divided into same use, they all require different fire-resisting times and at risk. addition, simple calculations proposed recalculating complex formula determine time.
