Bending behaviour of corrugated web beams

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

“…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. As shown in Fig.…”

“…By the accordion effect, the axial rigidity of web decreases and the stresses introduced to the top and bottom flanges increases. The existing studies on flexural behavior of beams with corrugated web [14][15][16][17], however, either did simple calculations to obtain the flexural strengths of their specimens, just ignoring the sectional area of web, or performed the finite element analysis on the certain types of section for the verification of their behavior, showing limitations in quantitative estimation of the accordion effect for design and analysis in general. In this study, therefore, a wide range of parametric study on the accordion effect has been performed using the finite element (FE) analysis for a various geometric characteristics of the beams with corrugated web.…”

“…As shown in Fig. 1a, however, prestressing on a steel beam with corrugated web can maximize the effective prestress introduced into the top and bottom flanges due to the accordion effect [14][15][16][17] caused by the low web axial rigidity, which also provides lager initial camber and better deflection control. Additionally, fabricating composite members by pouring concrete to the corrugated web of steel beam and upper slabs improves composite behavior as shown in Fig.…”

Design and Analysis of Parking Elevator having Combined Mechanism

“…He et al [12], Y. A. Khalid et al [13] and G. Nirupama et al [14] proposed the synergistic use of partially encased concrete and composite girders with corrugated webs to avoid buckling of corrugated webs and compression flange under large combined shear force and bending moment in hogging area.…”

Structural Performance of Prestressed Composite Members with Corrugated Webs Exposed to Fire

“…Figure 2a shows a PC bridge with corrugated webs and prestressed bottom flange, which was built at Ginzan-Miyuki in Japan as shown in Figure 2b. Figure fact, the market demand on the prestressed composite members with corrugated webs has been growing as reported in literatures [6][7][8][9][10][11][12]. According to Ibrahim [13] and Driver et al [14], their future application potential is very positive as the evolution of corrugated webbed composite members is still undergoing.…”
