A large part of common reinforced concrete (RC) structures are designed as intermediate moment resisting frames. However, current progressive collapse studies have not paid much attention to these frames. In this study, based on the acceptance criteria of the UFC 4-023-03 document, the infl uence of some external and corner column removal cases are evaluated by nonlinear procedures in all storeys of a regular structure. Although this structure considers the acceptance criteria of nonlinear dynamic analyses, nonlinear static analyses require additional reinforcement in beam supports in the top two storeys. Compared to dynamic analyses, it is also concluded that static analyses are more conservative in the estimation of maximum vertical displacement and shear force in beams.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
