“…To assess the real behaviour of the frame, it is therefore necessary to incorporate the effect of connection flexibility of the frame [2][3][4][5][6]. The flexibility of connections depend on the deformation of the fasteners (bolts, end plate, angle flange cleats, etc.…”

“…Irreversible deformation occurs when the deformation of a component enters the plastic range. Block [13] and Dong [15] employed the classic Masing rule [19], based on which the unloading curve is obtained by doubling the loading curve in scale and rotating by 180°, to represent this 'memory effect'. However, since the tension and compressive curves of the semi-cylindrical component are not identical in shape [18], the Masing rule is not suitable for this connection.…”

To enhance the robustness of connections in fire, the improved design version of a novel ductile connection has been proposed. Performance of the improved design version of novel connection has been compared with that of the previous design version using a sub-frame model. The comparison results show that the improved version of novel connection further enhances its ductility. Five case studies have been carried out, in which the novel connections are applied to sub-frames with different beam spans. Results show that the axial forces generated in the beams with novel connections are significantly reduced compared with those of the beams with rigid connections. The analytical models for the web-cleat component of the novel connection and the WCSC component, which considers the semi-cylindrical section and the web-cleat as a whole to deform, have been developed based on simple plastic theory. Then two schemes of componentbased model have been proposed for the novel ductile connection and loading and unloading behaviour have been incorporated into individual component. Result curves of the two schemes of component-based model have been compared and validated against Abaqus simulations and experiments. Finally, the proposed component-based model has been applied to two simple examples to illustrate how different spring rows work in the process of connection deformation.
