“…In corrugated plates, the yield shear stress can be determined with eq. (1) (Sayed-Ahmed, 2005, 2007Kiymaz et al, 2010) Buckling control of corrugated plates is performed by overall and local buckling. The local buckling mode of the corrugated plates is formed in flat panels of the trapezoidal corrugated plates, primarily, and along the horizontal edge, as shown in Figure 4.…”

“…In these conditions, the local buckling is studied in isotropic plates and the elastic critical shear stress for the local buckling mode is defined by eq. (2) for trapezoidal and sinusoidal plates (Sayed-Ahmed, 2001, 2007Kiymaz et al, 2010): where w t is the corrugated plates' thickness, b is length of wave in the trapezoidal corrugated plate in which the local buckling occurs, s is the actual length of the corrugate in the plate with a sinusoidal corrugated plate, E is the modulus of elasticity, ν is the Poisson ratio of steel and s k is the shear buckling coefficient in the local buckling mode, the value of which is dependent on boundary conditions and the panel's aspect ratio ( w b h ), such that w h is the height of the plate. This coefficient for trapezoidal corrugated plates is defined by eqs.…”

“…In this case, the critical shear stress is estimated with respect to the corrugated plate as an orthotropic plate. The critical shear stress of this mode is defined by (Sayed-Ahmed, 2005, 2007Kiymaz et al, 2010): where g k is the global buckling coefficient, which is a function of the panel aspect ratio and the boundary conditions. In a trapezoidal corrugated plate, it is 36 when the longer edges are simply supported and the shorted edges are clamped, such as in the web plate on a plate girder.…”

In this paper, the nonlinear behaviour of steel plate shear walls with corrugated plates under lateral pushover loading conditions in the models' top level has been analytically investigated by the finite element method. The one-storey frames have beams and columns as boundary elements. Steel plate shear walls are simulated using the finite element method, based on the available experimental models in the literature. After calibration of the analytical models, more parameters of steel shear walls with corrugated plates, such as the thickness of the corrugated plate, the stiffness of the boundary elements, the corrugation depth in the corrugated plates and the corrugation length of the infill of the corrugated plates, are investigated. The results of this study have demonstrated that in the wall with constant dimensions, the trapezoidal plates have higher energy dissipation, ductility and ultimate bearing than sinusoidal waves, while decreasing the steel material consumption. KeywordsSteel shear wall; sinusoidal corrugated plate; trapezoidal corrugated plate; energy dissipation; ductility; ultimate bearing. Evaluation and comparison of behavior of corrugated steel plate shear walls 1 INTRODUCTIONSteel shear walls have been used in the construction of high-rise structures in most advanced seismic countries, such as the United States, Japan and Canada, for almost three decades. This system has great advantages compared to other similar systems such as reinforced concrete shear wall and steel braces. The benefits of this system include high ultimate bearing, perfect plasticity, high energy absorption capacity, appropriate stiffness, reduced structural weight, lower foundation construction costs, better quality and high-speed construction. The overall structures of steel shear walls consist of boundary elements such as beams and columns, with infill steel plates in the spaces between them. Steel shear walls can be constructed in two types: unstiffened and stiffened. In unstiff- ened walls, a series of flat plates with light thickness is used for utilizing the post-buckling field under overall buckling. In the second type of wall, a belt series or steel profiles are utilized as stiffeners with different arrangements -horizontal, vertical and diagonal -on one side or both sides of the wall until the energy dissipation, stiffness and ultimate bearing are increased. The first method is completely uneconomical because to improve the hysteresis curve of the walls described it is necessary to increase the thickness of the steel plate until the plate does not buckle before yielding; this increase in thickness will be very significant and uneconomical. The second method, which involves strengthening the plate by a series of stiffeners, is economical and quite effective. By using this method, the hysteresis curves turn from an S-shape to a spindle shape and increase the hysteresis curve area. However, this method, primarily due to welding operations, causes weaknesses of the plate within. It also has higher costs for j...

“…Openings were considered on the flat plate parts of the trapezoidal web and the effect of various geometric parameters was investigated. Kiymaz, Coskun E, Coskun C and Seckin in 2010 [6] performed a FEA on series of models of beams with sinusoidal corrugation with different corrugation density and different relative opening diameters. In recent years there have been several publications on a similar topic by De'nan and Mustar in 2012 [7], by Krishnarani and Mohanan in 2016 [8] and by Krishnarani and Krishna in 2016 [9], by De'nan, Hasan and Keong in 2017 [10].…”

The paper presents a study of the transverse bending behaviour of corrugated web beam with and without web openings. Examined steel beams consist of two flanges and a thin triangularly corrugated web, connected by automatic welding. In the literature, the influence of web opening over transverse load carrying capacity was dealt with mostly for steel beams with plane, sinusoidal and trapezoidal corrugated webs, so researches of beams with triangularly corrugated webs were found out to be very limited. A parametric study is carried out for various web slenderness and corrugation densities. A general-purpose finite element analysis software ABAQUS was used. The corrugation densities adopted in this study represent practical geometries, which are commonly used for such structures in building practice. Models with and without web openings were analysed and examined in terms of load-deformation characteristics and ultimate web shear resistance. Recommendations are given for the practical design of corrugated web beams weakened by circular openings.

“…Especially, to overcome the span length limitation caused by the relatively heavy self-weight of a PSC box girder bridge, various studies have been performed using steel web members, such as corrugated or truss steel webs (Brozzetti 2000;Ohyama et al 2005;Ibrahim et al 2006;Kiymaz et al 2010;Jung et al 2010;Jung et al 2011;Xue et al 2011). The theory behind this was that if the concrete webs in PSC box girders could be replaced by steel truss webs, the weight of the superstructure could be decreased by about 20%, enabling a span extension.…”

This study focused mainly on prestressed concrete box girder bridges with steel truss web members, also known as Hybrid Truss Bridge (HTB). Previously, French engineers worked to improve the structural efficiency of prestressed concrete box girders by using concrete-steel hybrid subcomponents in an effort to reduce the weight of the superstructure. As a result of these efforts, several HTBs have recently been constructed in Japan and Korea. All of these bridges have unique connection systems between the concrete slabs and web truss members, which dictate the safety as well as the failure behavior of the hybrid girders. Thus, evaluation of both construction and structural safety of the connection systems regarded as an essential step in the design of HTB. In this study, four new connection systems using either hinge devices or T-type perfobonds have been proposed as improvements to the assemblage and to eliminate the need for welding during construction while satisfying load carrying capacity requirements. The static loading tests for six connection specimens in real scale were carried out in order to fully evaluate structural safety of the newly proposed connection systems. Also, a real scale railway bridge specimen with a 20m single span and an embedded hinge connection system was designed and constructed in a structural laboratory to perform for static and dynamic tests. Using this specimen, the possibility of using an embedded hinge connection system in a HTB, both for railway and general roadway usage, was evaluated.
