ABSTRACT: This
paper reports two new tests conducted to augment available
data highlighting the structural performance of multistory steel frames under progressive collapse. The investigated steel
frames had different geometries, different boundary conditions, different
collapse mechanisms, different damping ratios and different connections. Overall,
the paper addresses how multistory frames would behave when subjected to local
damage or loss of a main structural carrying element. The obtained results can
form a data base for nonlinear finite element models. The deformations of the investigated
steel frames and failure modes under progressive collapse were predicted from
the finite element analysis, with detailed discussions presented.
