Web openings in horizontally curved composite plate girders

Horizontally curved composite plate girders with trapezoidally corrugated webs

“…Therefore, the advantage of composite action between steel girders and concrete deck is not realised. It has been shown earlier by the authors [1,2] that a significant benefit could be achieved in terms of larger load carrying capacity besides enhanced stiffness. The steel part of the composite girders consists of deep webs stiffened by transverse stiffeners placed at regular intervals along the span.…”

Analysis, design and construction of curved composite girder bridges: State-of-the-art

“…A series of parametric studies were performed to derive a new equation for the minimum required rigidity of the longitudinal stiffeners from regression analyses. Basher, Shanmugam and Khalim (2009) studied on the effects of circular or square web openings on the ultimate strength of horizontally curved composite plate girders, mainly focusing on the opening sizes and their locations within the web panels, and put forward an approximate method to determine the ultimate strength capacity of horizontally curved composite plate girders accounting for the presence of web openings and composite action between the steel girder and concrete slab.…”

Static and Dynamic Analysis Web Opening of Steel Beams

“…Other works can be cited concerning the web openings beams behavior. Basher et al [13] investigated the effects of circular or square web openings on the ultimate strength of horizontally curved composite plate girders. Some numerical simulations in order to provide data for the development of a design model for the shear capacity of steel girders with web openings, with and without transverse stiffeners and opening reinforcements were performed by Hagen et al [14] and Hagen and Larsen [15].…”
