In this paper we present a comparative analysis regarding the shear web resistance between five types of steel plate girders and a girder with corrugated webs. The web buckling resistance of steel plate girders is established in accordance with EN 1993-1-5: Plated Structural Elements-§5.3. In the case of girders with corrugated webs, the background for the shear resistance of the web and the beam verification is the Annex D to EN 1993-1-5: Plate Girders with Corrugated Webs.

The corrugated steel plate is a widely used structural element in many fields of application because of its numerous favorable properties. To increase the shear capacity of web of large steel plate girders, the web with different patterns such as tapered web, haunches, corrugations of different shapes are used. Present paper deals with the determination of buckling strength of a plate girder considering rectangular corrugated web plate. The finite element analysis of a plate girder is carried out using ANSYS. The results obtained from analysis are then compared with the plate girder with plane web of uniform depth. Various parameters like buckling strength and weight are compared. It is concluded that the corrugated web plate has high buckling strength and sufficient reduction in weight with light gauge elements, than plate girder with plane web.

Abstract: The structural action of a beam is predominantly bending, with other effects such as shear, bearing and buckling also being presented. Due to the more application of corrugated section in steel design, this paper develops a three-dimensional finite element model using SAP2000 to investigate the effects of web corrugation on bending behavior of corrugated web profile (CWEB) steel sections. A corrugated web profile (CWEB) steel section is a built-up steel section made up of two flanges connected to a web plate of triangular profile. Thin shell element was chosen to represent the element type of the model. Three models were used for analysis one of flat web (FW) and two sizes of CWEB of different corrugation angle. Design is done based on IS: 800-2007(LSM). Loads considered in modeling are Dead load, Live load Wind load and Earthquake load along with the combination as specified in IS. Response spectrum analysis and time history analysis are carried out for zone 5, structural parameters like self weight, vertical deflection, lateral deflection and design forces results are compared for all the models.

Steel plate girders with trapezoidal corrugated webs have been used widely over the last years around the world in many roadways and railway steel bridges as they can introduce several important advantages compared with plate girders bridges with flat web. The study in this paper presents a numerical investigation of flange buckling behavior using the FE software ABAQUS and studies the effect of slenderness ratio of the flange and corrugated web on the bending moment capacity and the flexural behavior of trapezoidal corrugated web steel plate girders built-up from high-strength steel (HSSs). Firstly, the linear buckling analysis has been carried out to obtain the local flange buckling coefficient using the general equation of stresses and the stresses obtained from the numerical results, then the ultimate bending moment has been obtained from the nonlinear buckling analyses. The numerical results showed that the flange slenderness ratio and web slenderness ratio play a major role in controlling the bending moment capacity of corrugated web plate girders. Finally, some recommendations have been listed to help structural engineers to design corrugated web bridge girders efficiently.

Corrugated steel plates are widely used in pre-stressed box girder bridges due to its ability to achieve an adequate shear buckling resistant and reduce the dead weights. The present study aimed to determine the static behaviour of two and four panels composite plate girder with a corrugated web by using LUSAS software. The numerical models were validated according to the outcomes of a previous experimental test. The validation results indicated a good consistency in terms of load-deflection response, shear strength and failure mode. Intensive parametric studies were carried out to determine the effects of corrugation angle (α), corrugated web thickness (tweb), flange thickness (tflange) and concrete strength on the behaviour of composite plate girder. The results indicated a positive increase in the shear strength and change in the failure mode of the both investigated girders with the increase of corrugation angle, web and flange thickness. On the other hand, a slight effect was n...

This paper presents analytical studies the elastic interactive shear buckling stress of corrugated steel web is calculated by all possible failure criteria (steel yielding, local and global buckling stresses), using Minimum Potential Energy Method to determine critical shear stress of local and global buckling of plate girder with corrugated webs. The results are compared with Finite element method (FEM) using ANSYS/V12. It found that the proposed equations are a good agreement with the results FE.

Built-up steel girders have many applications in structural engineering, both in bridges and buildings. Flat web steel girders, which are the traditional choice, involve several weaknesses. Girders with corrugated webs were found to be more effective in their load-carrying capacity and deflection than girders with flat webs. In light of this, an effort is made in this work to examine how the addition of triangular corrugated webs influences the load-bearing capacity and deflection of steel girders. This study aimed to determine whether or not the strength of built-up steel with corrugated webs could be improved. A concentrated midspan load was applied to six simply supported steel beams of varying span-to-depth ratios (1.0, 1.833, and 2.5) and web corrugation amplitudes (30 and 60 mm). An increase in ultimate strength of 15.7% to 35.1% was found for webs with triangular corrugations of 30 mm and from 2% to 29.1% for webs with corrugations of 60 mm. A reduction in deflection of up to 35.3% can be attained when using triangular corrugated webs. It was also found that using webs with 30 mm corrugations was more efficient than using webs with 60 mm corrugations. The effect of corrugation was found to fade when the span-to-depth ratio increased to 2.5. This led to the conclusion that using webs of 30 mm amplitude of triangular corrugation could improve the strength and serviceability of steel girders.
