“…Corrugated steel plates without additional stiffeners are characterized by high shear buckling strength and out-of-plane flexural stiffness, having been widely used in structural engineering applications, such as large span roof, steel plate shear walls, and bridge girders (Wu et al 2006, He et al 2012, Emami et al 2013, Jiang et al 2015. The concept of replacing flat webs with corrugated webs in bridge structures was first proposed in France at 1986, then successfully applied worldwide in the past 30 years (Combaut 1988, Kondo et al 1994.…”

<p>Corrugated webs are used to increase the shear stability of steel webs of beam-like members and to eliminate the need of transverse stiffeners. Previously developed formulas for predicting the shear strength of trapezoidal corrugated steel webs, along with the corresponding theory, are summarized. An artificial neural network (ANN)-based model is proposed to estimate the shear strength of steel girders with a trapezoidal corrugated web, and under a concentrated load. 210 test results from previous published research were collected into a database according to relevant test specimen parameters in order to feed the simulated ANNs. Seven (geometrical and material) parameters were identified as input variables and the ultimate shear stress at failure was considered the output variable. The proposed ANN-based analytical model yielded maximum and mean relative errors of 0.0% for the 210 points from the database. Moreover, still based on those points, it was illustrated that the ANN-based model clearly outperforms the other existing analytical models, which yield mean errors larger than 13%.</p>

“…Because of using corrugated steel webs instead of concrete webs, no restraint between the concrete slabs and corrugated steel webs exists, resulting in reduction of effects on structural responses due to shrinkage and creep of concrete, temperature differences between webs and slabs. In addition, the "accordion effect" of the corrugated steel webs allows pre-stressing efficiently introduced into concrete slabs [1,2]. Since the first composite bridge with corrugated steel webs-Cognac Bridge built at France in 1986, a large number of this type composite bridge has been constructed, and their mechanic behaviors such as shear, flexural, torsional behavior, fatigue performance and so on have been experimentally and analytically studied [3][4][5][6][7][8][9].…”

Composite girder with corrugated steel web is one of the promising concrete-steel hybrid structures with superior properties and cost effectiveness widely applied in highway and railway bridges. The connection between concrete slabs and corrugated steel web is an important part of such composite structure. In order to improve pouring quality and durability of concrete for joint structure between corrugated steel webs and concrete lower slab, the validity of placing lower slab on the inner side of corrugated steel webs was confirmed and a new joint structure with perforated plate connectors was proposed. Push-out tests on proposed joint structure with different parameters including the welding width and the plate thickness were carried out to study their shear strength, shear stiffness, failure modes and relative slip characteristics. Subsequently, three-dimensional finite element models taking material non-linearity and nonlinear contact between steel and concrete interface into consideration were built and validated by the push-out tests. Afterwards, parametric studies were performed to further investigate the influences of geometrical parameters (such as width, height and thickness of perforated steel plate) and material parameters including steel yielding strength and concrete compressive strength on ultimate shear strength and failure mode of the joint structure. Analytical results indicate that the shear loading capacity is increased with the thickness, the width and height of perforated plate, and the compressive strength of concrete. However, steel yielding strength, presence or absence of perforating rebar, have a negligible effect on ultimate shear strength of the joint structure. Finally, prediction equations of shear capacity were provided and compared with experimental and numerical results. The calculated shear capacity agrees well with experimental and numerical ones, indicating provided analytical equations can accurately predict shear capacity for such novel joint structure.
