Steel and Steel-Concrete Composite Structures at Elevated Temperatures

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 connection
that causes failure of the bolts, end plate and
column flange in the tension zone of the connection
and elastic analysis of a panel zone in a rigid or
semi-rigid joint in a steel frame, are presented in
this book. In order to model the structural response
of a composite beam restrained by cooler members a
partial interaction analysis is developed.
The generic techniques that are developed in this
book provide a structural model for the response of
beams and beam-to-column connections in fire and can
be especially useful to professionals in Structural
and Fire Engineering fields.
