“…The steel beam with corrugated web had been applied to structures in Europe as early as 1960s [1], and then was also applied to bridge constructions in Japan as well as Europe in the 1980s [19] and recently in the USA [20]. The flexural members with corrugated web have many advantages in addition to the aforementioned.…”

“…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].…”

“…Many numericaliinvestigations were reported in the literatureehighlighting the structural performance of different types of steel bridges subjected to differenttloadings and different boundary conditions [4][5][6][7][8][9].The numerical investigationsiproposed Finite Element (FE) models, for the SG and the compositeegirder, which were developed to provide accurate analyses and betteriunderstanding for the behavior and stability of differentigirders [10]. Experimental work regarding the interaction of bending moment and shear force (M-V interaction) for longitudinally stiffened girders was conducted by Sinur [11].…”

Optimization is a process through which the best possible values of design variables are achieved under the given of constraints and in accordance to a selected optimization objective function. Steel I-girders have been used widely in different fields, which are generally fabricated by connecting two plate flanges, a flat web and a series of longitudinal or transverse stiffeners together. The use of steel girder with external prestressing has been used in many countries as a means of strengthening bridges. The purpose of this paper is to develop a finite element model for the optimization of a steel girder with external prestressing. The ANSYS finite element software package was used to find the optimum cross section dimension for the steel girder. Two objective functions are considered in this study there are optimization of the strain energy and total volume of the girder. The design variables are the width of top flange, the thickness of top flange, the width of bottom flange, the thickness of bottom flange, the height of the web, the width of the web and area of prestressing tendons. Two type of steel girder are considered there are steel girder without prestressing and steel girder with prestressing.The results for volume minimization shows that the optimum cross section for steel girder with prestressing smaller than for steel girder without prestressing.

“…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.…”

In this study, to assess the fire performances of corrugated webbed prestressed (CWPS) composite beams exposed to fire, full-scale fire resisting tests were carried out, and fire-resisting behavioural responses of the test specimens were analyzed and compared with those obtained from nonlinear finite element analyses. Key test variables were the cover thickness of the fire protection material applied to the bottom flange of corrugated webbed steel beams, which was directly exposed to fire, and the shapes of corrugated webs. All the composite beams with fire protection material covers exposed to standard fire showed good fire-resisting capacities with fire ratings over 3 h and in particular, CWPS composite beams with relatively thin fire protection material cover thickness, compared with the non-prestressed slim-floor composite beam, satisfied the required fire performance criteria in ISO 834 standard and Eurocode. Additionally, the test results showed that the shape of corrugated webs used in CWPS composite beam specimens could have a great impact on their fire-resisting performance. The nonlinear finite element analyses performed in this study accurately estimated the overall behaviours of test specimens and especially assessed the effects of the shape of the corrugated web on the temperature distributions and fire resistance performances of CWPS composite beams appropriately.
