Evaluation of Rigidity of Extended End-Plate Connections
Publication: Journal of Structural Engineering
Volume 123, Issue 12
Abstract
Extended end-plate connections are usually regarded as rigid connections. This recognition has not been investigated systematically in frame analysis. The aim of this study is to evaluate the degree of rigidity of extended end-plate connections utilizing the experimental moment-rotation data of steel beam-to-column connections stored in an updated database. It is revealed from this study that all of the real extended end-plate connections stored in the database may not serve the purpose of rigid connection. About 49 of these connections have an initial connection stiffness <105.05 kN-m/rad (106 kip-in./rad). These connections may be regarded as semirigid connections. Those connections whose initial connection stiffness are >105.05 kN-m/rad (106 kip-in./rad) may be classified as rigid connections depending upon their ultimate moment capacity. These conclusions are compared with two systems of connection classifications.
