Opis

The behaviour of structures at elevated temperatures is profoundly different from that at ambient state.Local buckling of beam flange outstands and localbuckling of beam web, which experiences a non-uniformtemperature variation, are important because themechanical properties of the steel are degradednon-uniformly from their ambient values. Developing aformulation representing the mechanics of thepotential failure zone in the column web in thecompression 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 andcolumn 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.
