Advanced inelastic analysis of frame structures

Abstract

This paper provides a state-of-the-art summary of recent advances in inelastic analysis of space frame structures. Particular attentions are devoted to inelastic modelling of framework components for accurate representation of frame behaviour and the applications of plastic hinge analysis for large-scale framework. Issues related to inelastic buckling and post-buckling unloading of struts, modelling of gradual yielding in steel beam-columns, inelastic modelling of composite floor beams subject to sagging and hogging moments, modelling of building core walls and semi-rigid beam-to-column connections in three-dimensional frameworks are discussed. Numerical examples are provided to illustrate the acceptability of the use of the inelastic models in predicting the ultimate strength and inelastic behaviour of spatial frameworks. © 2000 Elsevier Science Ltd.
