Refined 3D finite element modeling of partially-restrained connections including slip

Generalised component-based model for beam-to-column connections including axial versus moment interaction

“…Since then, several researchers have been using the FEM to investigate the joint behaviour, such as: Lipson & Hague (1978) -single-angle bolted-welded connection; Krishnamurthy et al (1979) -extended endplate connections; Richard et al (1983) -double-angle connection; Patel & Chen (1984) -welded two-side connections; Patel & Chen (1985) bolted moment connection; Kukreti et al (1987) -flush endplate connections; Beaulieu & Picard (1988) -bolted moment connection; Atamiaz Sibai & Frey (1988) -welded one-side unstiffened joint configuration. More recently, focusing on 3D finite element models the following works can be mentioned: Sherbourne & Bahaari (1994); Bursi & Jaspart (1997Yang et al (2000); Citipitioglu et al (2002); Coelho et al (2002);and Maggi et al (2002).…”

Modified Three-Parameter Power Model to Predict Moment-Rotation Curve of Top- and Seat-Angle Connection

“…Recently, the T-stub modeling concept has been used to represent mechanical behavior of extended end plate connections and modified to use for angle type of connections [11,12,2]. However, the Tstub model is somehow different in respect to representing the actual deformation pattern of true angle type of connections stating from plastic yielding to the failure [13], and may loose its efficiency in estimation of connection strength.…”

Response and component characterisation of semi-rigid connections to tubular columns under axial loads

“…It was observed that the flexibility of the reverse channel component has a direct influence on both the initial rotational stiffness and moment capacity of the connection, and the three main inelastic mechanism exhibited by this type of connection were identified. Nevertheless, as with blind-bolted details, there is a dearth of Many studies have been carried out on the numerical simulation of semi-rigid connections incorporating conventional bolts [17][18][19][20][21]. Krishnamurthy [17] first used the finite element (FE) method to estimate the moment-rotation response of steel bolted end-plate connections.…”

“…Krishnamurthy [17] first used the finite element (FE) method to estimate the moment-rotation response of steel bolted end-plate connections. Citipitioglu et al [18] presented a new displacement-based 3D FE model constructed in ABAQUS [22] able to predict the behaviour of partially-restrained connections; the effects of slip were incorporated by defining contact surfaces, and bolt pretension was applied by means of equivalent bolt shortening deformation. In contrast, Kishi et al [19] directly applied the bolt pretension via a special scheme developed within ABAQUS.…”
