“…The lateral bracing system was installed to restrict the lateral displacement of the beam, without affecting its vertical displacement. This test setup, to apply simultaneous shear force and rotation to the connection, is based on that used in prior research [26]. measure the out-of-plane deformation of the beam, as well as that of the shear plate and of the 175 girder web.…”

Stiffened extended shear tab connections (either in full-depth or partial-depth configurations) are widely used to connect simply supported beams to the web of supporting girders or columns. Full-scale laboratory tests of stiffened extended shear tab connections underscored the differences between their observed and expected design strength calculated according to current design specifications. In particular, the design procedure of such connections neglects the influence of the out-of-plane deformation of the supporting girder web on yielding and inelastic buckling of the shear plate. These are the main governing failure modes for the full-depth configurations of stiffened extended shear tabs, when placed on one side of a supporting girder or column. This paper aims to address the effect of the girder web flexibility on the load transfer mechanism and failure modes of extended beam-to-girder shear tab connections. The findings are based on finite element (FE) simulations validated with full-scale experiments on beam-to-girder shear tab connections. The influence of interior versus exterior girder webs on the connection behaviour is assessed. Emphasis is placed on the influence of the girder web deformation and shear tab configuration on the load transfer mechanism and the ultimate strength of extended beam-to-girder connections. The current design practice is evaluated and improved recommendations are provided for the design of full-depth extended beam-to-girder shear tabs.

“…This was deemed a rational approach based on prior research [31,32]. This target rotation should be achieved at the connection probable shear resistance, which was calculated based on the expected material properties in lieu of measured ones, as coupons tests could be conducted only after full-scale tests.…”

Owing to the lack of a comprehensive published procedure for the design of stiffened extended shear tabs, practicing engineers usually follow design guides for unstiffened shear tabs. The results of recent laboratory experiments and numerical analyses have demonstrated that improvements to this design approach are warranted. Furthermore, design methods for this connection type under loading scenarios including combined axial and shear forces are not well established. To address these shortcomings, full-scale laboratory tests were carried out on the double-sided configuration of stiffened extended beam-to-girder shear tabs with full depth shear plates. These experiments were complemented by a thoroughly validated finite element (FE) study. Based on the results of these experiments and FE simulations, the connection failure modes were characterized and the axial force along with the other main parameters that affect the connection behaviour were further examined. The current design practice for the double-sided configuration of the full-depth extended beam-to-girder shear tab was also evaluated.

“…In the past, Astaneh and co-workers [4,11,12] employed two actuators to form a similar setup which could apply shear and rotation to the connection proportionally and simultaneously. Due to the limitations of the instruments for this study, it was very difficult to adopt the same loading path as that of Astaneh's work.…”
