The behaviour of structures at elevated temperatures
is profoundly different from that at ambient state.
Local buckling of beam flange outstands and local
buckling of beam web, which experiences a non-uniform
temperature variation, are important because the
mechanical properties of the steel are degraded
non-uniformly from their ambient values. Developing a
formulation representing the mechanics of the
potential failure zone in the column web in the
compression region of the connection due to the
large compressive forces developed during fire,
predicting the critical temperature in a...
