Lateral–torsional buckling of I-girder with corrugated webs under uniform bending

Flexural behavior of prestressed composite beams with corrugated web: Part I. Development and analysis

“…As shown conceptually in Fig. 4, the flexural members with corrugated web have improved structural stability against non-symmetrical load because their shear buckling strength by the in-plane and out-of-plane load are relatively greater than typical wide flange beams [19][20][21][22][23][24][25][26][27][28][29]. Furthermore, the web can be considerably thinner than that of existing wide flange beam and the amount of stiffener can be drastically reduced so that it allows a more economical use of expensive steel members than previously possible [1].…”

“…Recently, Abbas et al [20], Sayed-Ahmed [31], and Moon et al [23] extended their studies to the evaluation of lateral-torsional buckling strength of steel beams with corrugated web subjected to in-plane load. There have been, of course, many other researches on the shear buckling strength of steel beams with corrugated web [19][20][21][22][23][24][25][26][27][28][29], and they reported that the in-plane and out-of-plane shear buckling strengths of the beams with corrugated web were superior to the typical wide flange beam due to the geometric advantages of corrugated web. Huang et al [14], Egaaly et al [15], El-Metwally and Loov [16], and Khalid et al [17] conducted experiments on the accordion effect of steel beams with corrugated web and performed finite element analysis as well.…”

Finite Element Analysis of Lateral Torsional Buckling Behaviour of Tapered Steel Section with Perforation

“…Moon et. al [10] had investigated theoretical and finite element analysis of the lateral torsional buckling of I-girder with corrugated webs under uniform bending. They had found the elastic lateral-torsional buckling strength is increased up to 10% for I-girders with corrugated webs compared to I-girder with flat webs.…”

Shear buckling strength and design of curved corrugated steel webs for bridges

“…The first PSC girder bridge constructed with corrugated steel webs has recently been constructed in South Korea [1]. In addition, applications of corrugated steel webs have been extended to extra-dosed and cable-stayed bridges [2], and, there have been several attempts to apply corrugated webs to plate girder bridges [3][4][5]. It is assumed that the web carries only shear forces due to the accordion effect [6].…”

“…webs [1][2][3][4][5][6][7][8][9][10][11][12]. Easley and McFarland [7] who initiated the buckling behavior of corrugated plates, proposed the global shear buckling equation of corrugated webs by treating the corrugated web as an orthotropic flat web.…”
