Interactive Shear Buckling Of Plate Girder with Corrugated Web (Analytical Solution

Buckling Analysis of Plate Girders with Corrugated Web

Plate girders became popular in the late 1870's, when they were used in construction of railroad bridges. The plates were joined using angles and rivets to obtain plate girders of desired size. By 1940's welded plate girders replaced riveted and bolted plate girders in developed world due to their better quality, aesthetics and economy. The corrugated steel plates are widely used structural elements in many fields of application because of its numerous favourable properties. To increase the shear capacity of web for large steel plate girders, the web with different types such as tapered web, haunches, corrugations of different shapes are used. Corrugated steel panels have been recognized as excellent load carrying members". In this project the stiffness of plate girders with different corrugation parameters were compared and it was established that corrugated web plate girders are better than plane web plate girder.

Shear Buckling Analysis of Corrugated Web I-Girder with 3D Nonlinear Finite Element Method

Journal of Civil Engineering, 2021

This paper presents a shear buckling analysis of corrugated web I-girder beam using nonlinear finite element analysis. An in-house finite element package called 3D-NLFEA is used in the simulation. The steel material is modelled as solid elements with one-eight aspect ratio between the element size and its thickness. The double sine waves equation is used to generate the initial imperfection in the corrugated web. The nonlinear geometry deformation, which is essential in capturing the buckling behavior, is considered using the 2 nd order analysis in 3D-NLFEA. A comparison with the carried out experimental test in the laboratory showed that the peak prediction from the analytical model was in good agreement. Furthermore, using the double sine waves equation as the initial imperfection can closely predict the buckling mode and shapes of the corrugated web I-girder as obtained from the experimental test.

Numerical Study of Flange Buckling Behavior of High-Strength Steel Corrugated Web I-Girders

2021

Steel plate girders with trapezoidal corrugated webs (TCWPGs) have been used over the last years around the world in many roadway and railway steel bridges as they can introduce several important advantages compared to flat web plate girders. The proper design of corrugated web girders depends mainly on the flexural and shear capacity of them. However, the flexural capacity is more important. Also, not many researchers studied the flexural capacity of such girders especially, when flange local buckling failure type (FLB) occurs in these corrugated web girders. In this paper, the flange local buckling behavior of steel trapezoidal corrugated web girders built up from high-strength steel (HSS) plates has been investigated to get the advantages of both the technique of corrugated web plates (CWPs) and the high-strength steel material (HSSs) together. A new numerical parametric study on four important parameters has been carried out to explain and investigate the flange local buckling b...

Theoretical Investigation of Shear Buckling for Hybrid Steel Plate Girder with Corrugated Webs

2015

The corrugated steel plate is a widely used structural element in many fields of application because of its numerous favorable properties. The corrugated web beam behaves, in which the bending moments and applied forces are transferred only via the flanges, while the transverse forces are only transferred through the corrugated web.In the other hand, hybrid girders are assembled with different types of steel forthe flanges and the web of a steel plated I-shaped element, it can be arguably stated that hybridgirders yield a greater flexural capacity at a lower cost and weightcompared to a homogeneous girder. This paper aim to estimating the critical load of simply supported hybrid I-girders with corrugated webs under pure shear. A parametric study using three-dimensional finite element model using ANSYS version 12.0 were performed to investigate the effect of compactness of flanges, slenderness ratio of web and initial imperfection of web on the behavior of finite element modelsunder ...

Elastic Shear Buckling of Tapered Steel Plate Girders with Opening in Web

2023

Tapered Plate girders are considered the best efficient choice in design of the industrial buildings and bridges with large-span. Openings in the web of plate girders are frequently required to give space for services, resulting in increased fabrication costs and a reduction in load-carrying capability. The aim of the present paper is to estimate the critical shear buckling of tapered plate girders containing a circular or square opening. Finite element simulations were performed on 176 steel beams with prismatic and tapered web containing two different shapes of openings (circular and square). The analysis considered the effects of tapering angle, hole size with respect to the average height of the web, aspect ratio, depth to thickness ratio and the boundary conditions between the web and flanges. The numerical results are used to estimate an analytical expression for the critical shear stress of prismatic and tapered web panels containing a circular or square opening.

Shear behavior of steel plate girders considering variations in geometrical properties

Journal of Constructional Steel Research, 2019

This paper presents equations to determine the ultimate shear strength reduction factor of web plate in steel plate girders due to initial imperfection. The proposed equations are based on a parametric study of shear behavior of steel plate girders considering variation in geometrical properties of the section. 112 models with various initial imperfections, flange-to-web stiffness ratios, and web slenderness were analyzed using finite element software ABAQUS. Both geometric and material nonlinearity have been considered. According to the results, the ultimate shear strength proposed by AISC code is conservatively less than the obtained results by FEM, especially for slender plates; the difference between these two values could reach up to 60% in some cases. That is while, for compact and non-compact web plates, maximum difference is about 10%. Furthermore, it is observed that AISC elastic shear buckling strength is conservatively less than the results derived from FEM. This difference in slender and compact web plates reaches to almost 40% and 20%, respectively. This study reveals that the initial geometrical imperfection is an effective parameter on the shear strength of web plates. According to the results, the sensitivity of girders to initial imperfection is greater in non-compact-web girders than the slender or compact ones, and the maximum shear strength reduction is observed about 23% for maximum allowable imperfection as recommended in part1-5 of EC3. Based on the obtained results, a maximum permissible construction tolerance is proposed as well.
