AbstractFlush end-plate beam-to-column joints are widely used in gravity load resisting parts of steel frames. Although generally designed to behave as pinned connections, this type of joint is generally semi-rigid and partial strength, thus providing a reserve of strength against progressive collapse. In order to enhance the joint performance under column loss scenario, a design criterion is proposed and its effectiveness is investigated and discussed by means of parametric finite element analyses. The investigated parameters are the bolt diameter, the end-plate thickness, the number of bolt rows, the type of beam profile and the orientation of column axis. The obtained results enable to characterize the moment-rotation response curve and ultimate rotation capacity under compressive arching and catenary action.
HighlightsThe behaviour of flush end-plate joints under column loss scenarios is investigated.Both compressive arching and catenary actions are examined.A design criterion to enhance the robustness of flush end-plate joints is proposed.The effectiveness of the design criterion is verified by finite element analyses.Design recommendations are discussed.
