“…Znaczącym udoskonaleniem tego rozwiązania był układ sprężyn zaproponowany przez E. Bayo z zespołem [13]. Reakcję środnika słupa na przyłożone obciążenie zamodelowano tu, podobnie jak w poprzednio opisywanym modelu, poprzez współdziałanie dwóch sprężyn, to znaczy odpowiednio jednej odpowiadającej za pracę jego części ściskanej (cwc) i drugiej, modelującej zachowanie strefy ścinanej (cws).…”

“…At ambient temperature however, researchers have included the detailed connection response into global frames using component-based connection elements 9,10,11 . The main characteristic of these connection elements is that they are single finite elements, instead of assemblies of spring elements, which obtain their stiffness matrix from a number of translational springs.…”

This paper describes the development of a component-based element for endplate connections in fire. The reported research is part of an ongoing project aimed at understanding joint behaviour in fire. The paper summarises the derivation of the stiffness matrix of this new element, based a on spring model, and the incorporation of the element into the non-linear finite element program Vulcan. It also states the component characteristics that have been used for the individual zones of deformation in an endplate connection. Furthermore, the additional features of the element, necessary for correct response at elevated temperatures, like the consideration of the temperature distributions across the connection as well as cooling and unloading are summarised. The proposed element is then used to predict the momentrotation curves of connection experiments at ambient and elevated temperatures. Finally, the advantages and limitations of the new high temperature connection element are listed.

“…There is a large volume of published work on semi-rigid connections indicating that this interest is being maintained and even expanded more and more (E Bayo et al 2006;SW Jones et al 1983;SW Jones et al 1980;ME Kartal et al 2010;Sang-Sup Lee & Tae-Sup Moon 2002;LMC Simoes 1996). These studies mostly deal with the effect of semi-rigid connections on the structural performance of steel structures.…”

The current study attempts to recognise an adequate classification for a semi-rigid beam-to-column connection by investigating strength, stiffness and ductility. For this purpose, an experimental test was carried out to investigate the moment-rotation (M-θ) features of flush end-plate (FEP) connections including variable parameters like size and number of bolts, thickness of end-plate, and finally, size of beams and columns. The initial elastic stiffness and ultimate moment capacity of connections were determined by an extensive analytical procedure from the proposed method prescribed by ANSI/AISC 360-10, and Eurocode 3 Part 1-8 specifications. The behaviour of beams with partially restrained or semi-rigid connections were also studied by incorporating classical analysis methods. The results confirmed that thickness of the column flange and endplate substantially govern over the initial rotational stiffness of of flush end-plate connections. The results also clearly showed that EC3 provided a more reliable classification index for flush end-plate (FEP) connections. The findings from this study make significant contributions to the current literature as the actual response characteristics of such connections are non-linear. Therefore, such semirigid behaviour should be used to for an analysis and design method.
