State-of-the-art of advanced inelastic anaysis of steel and composite structues
J.Y. Richard Liew(Singapore)

    This paper provides a state-of-the-art review on advanced analysis models for investigating thernload-displacement and ultimate load behaviour of steel and composite frames subjected to static gravity andrnlateral loads. Various inelastic analysis models for steel and composite members are reviewed. Compositernbeams under positive and negative moments are analysed using a moment-curvature relationship whichrncaptures the effects of concrete cracking and steel yielding along the members length. Beam-to-columnrnconnections are modeled using rotational spring. Building core walls are modeled using thin-walled element.rnFinally, the nonlinear behaviour of a complete multi-storey building frame consisting of a centre core-wall andrnthe perimeter frames for lateral-load resistance is investigated. The performance of the total building system isrnevaluated in term of its serviceability and ultimate limit states.
