Uesugi, H., Someya, T., Saitoh, H., Kubota, S. and Sakumoto, S., 1994. Load Bearing And Deformation Capacity Of Fire Resistance Steel Tubular Columns At Elevated Temperature. Fire Safety Science 4: 1149-1158. doi:10.3801/IAFSS.FSS.4-1149
The design method of building structures has been trending from a1lowable stress design method to ultimate state design method. The ultimate state design method is based on the assumption that load bearing and deformation capacity of plastic hinges are ensured sufficiently. Using the ultimate state design method in fire engineering design, it is necessary to investigate load bearing and deformation capacity at elevated temperature. In this study, the load bearing and deformation capacity of tubular columns made from fire resistance steel are shown, which are obtained experimental1y under pure compression and bending compress ion at elevated temperature.
