Response characteristics of flush end-plate connections

Flush end-plate (FEP) connections are one of the most popular bolted steel in construction practice. These possess a semi-rigid moment-rotation behavior that betwixt rigid and pinned connections. Nonetheless, they commonly idealized as design numerical simulations. This paper investigates flexibility, strength ductility such holistic manner, based on recently compiled comprehensive database more than 420 specimens were tested within past 50 years. The describes systematic methodology used to deduce response parameters from curves. includes deduction elastic, post-yield stiffnesses, effective yield maximum moments well ultimate rotation at failure. deduced made publically available support further analysis by other researchers. median value each parameter associated variability quantified with respect different connection topologies loading histories. data then assess classification performance terms existing standards.
