8 Existing approaches for collapse modeling Adaptive shifted integration (ASI) method � Isobe and Toi (2000), Natahira et al (2008) � Physical equivalent of a linear Timoshenko beam and rigid bars connected via rotational spring � Proposed to shift the integration point in a beam element depending on the stage of plasticity/facture to handle strong discontinuity in progressive collapse analysis Linear Timoshenko beam and its physical equivalent Natahira et al (2008)
9 Scope of research This research seeks “to create” effective and practical computational formulations for collapse modeling of steel structures � CZM continuum model + CZM-based macro-model formulations for structural collapse (<strong>Northeastern</strong> Uni.) � A stochastic framework to identify accurate collapse limit states and critical damage measures via incremental dynamic analysis (UIUC)
