| Abstract: | The behaviour differences between connections and elevated temperatures and the corresponding design requirements of a steel structure are illustrated.It is pointed out that direct application of the design concept for the ambient temperature to a fire safety design is unreasonable because in a fire situation,robustness should be the main concern for connections.The observations and conclusions drawn from a set of tests designed for this purpose are then reported.The relationships among three major paramete... |
