Abstract:The paper investigates the available ductility of the steel beams under cyclic action. The study is based on the concept of the plastic collapse mechanism, previously developed for monotonic loading, and further implements the concept of the initial cumulative deformation; it aims to calculate the main parameters that affect the rotation capacity of steel I and H beams made by European sections. The findings show that the loading type defined by the increasing or the constant amplitude, the number of cycles pr… Show more
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.
