Prediction of Temperature Properties of Exterior Steel Structural Members Exposed to Fire - Outline of a Three-Dimensional Heat Flow Analysis Model -

Recently, the buildings that structural steel is installed in the outside of exterior wall can be seen like the building of Nippon Television Network Corporation in Shiodome. If fire happens in such buildings, the exterior steel structures easily lose its structural function with temperature rise caused by exposure to fire jet plume and radiation of heat from ejected fire. Then, regarding the predicting method for temperature properties of exterior steel structures received the fire heating, properties of the current air that ejected from the window of the fire compartment and the radiant heat from the window were considered. This paper presents a temperature calculation model of which the rule element concerning heating these, and the calculation results was compared with the experiment results that steel received the radiant heating.
