2) 4) 5) 6) 8CFT This paper proposes a simple model of a load-displacement relation for predicting the local tensile elasto-plastic behavior of moment �������������������������������������������������������������������������������������������������������������������������������������������� type bolts. This model is developed by superposing the load-deformation relations of steel tube, these bolts and split-tees in the connections. ������������������������������������������������������������������������������������������������������������������������������������������ are modeled as tension members with tetra-linear or tri-linear load-deformation relation. This research verifies the analytical model by comparison with experiment results. The analytical results approximately reproduce the experimental results up to large deformations.
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.
