“…All girders were characterized by a span of 2228 mm, which resulted from the construction of the test stand. In places of support and application of external load, the elements were reinforced with vertical single bilateral stiffeners at full height from flat sheets with a thickness of 5 mm and variable width depending on the shape of the web [ 31 ]. Due to negligible values of longitudinal circumferential stresses in the corrugated web panels [ 32 ], susceptible support ribs were used [ 30 , 33 ].…”

This paper presents the results of experimental investigations performed on beams with corrugated webs. The aim of the research was to determine the effect of the geometric parameters of the sinusoidal web on the behavior of I-beams subjected to four-point bending. Special attention was paid to the effects of web thickness and wave geometry on the deflection of beams. The obtained failure modes of particular test samples are presented. Reference has also been made to the determined standard load capacities based on Annex D of the EC3 standard. In order to compare the performance of beams with corrugated webs, the results for beams with flat webs of the same thickness of web sheets are also presented.

“…In this span, corrugated plates are connected to their short edges of column flange. In these conditions, the local buckling studied in isotropic plates and elastic critical shear stress for the local buckling mode is defined by (2) in trapezoidal and (3) in sinusoidal plates [11,12,[14][15][16]:…”

Reinforcement of structures aims to control the input energy of unnatural and natural forces. In the past four decades, steel shear walls are utilized in huge constructions in some seismic countries such as Japan, United States, and Canada to lessen the risk of destructive forces. The steel shear walls are divided into two types: unstiffened and stiffened. In the former, a series of plates (sinusoidal and trapezoidal corrugated) with light thickness are used that have the postbuckling field property under overall buckling. In the latter, steel profile belt series are employed as stiffeners with different arrangement: horizontal, vertical, or diagonal in one side or both sides of wall. In the unstiffened walls, increasing the thickness causes an increase in the wall capacity under large forces in tall structures. In the stiffened walls, joining the stiffeners to the wall is costly and time consuming. The ANSYS software was used to analyze the different models of unstiffened one-story steel walls with sinusoidal and trapezoidal corrugated plates under lateral load. The obtained results demonstrated that, in the walls with the same dimensions, the trapezoidal corrugated plates showed higher ductility and ultimate bearing compared to the sinusoidal corrugated plates.

“…In all cases, the failure was due to vertical bending of the flange and crippling of the web under the load. These numerical and experimental investigations were extended to the typical parameter range used in bridges by Kövesdi et al [8]. Based on the large number of numerical and experimental results a modified design method is developed to determine the patch loading resistance of corrugated web girders.…”

The corrugated steel plate has been increasingly used as web of steel and composite bridges. When such a bridge is incrementally launched, the web panels are often subjected to combined shear and patch loading. There are only a few investigations available in the literature which are dealing with this interaction type, therefore the current research of the authors focuses on the analysis of the combined shear and patch loading in case of corrugated web girders. Based on patch loading tests executed on 12 short span specimens, a numerical model is developed and verified. A numerical parametric study is conducted to analyse the structural behaviour and the interaction between shear and patch loading in the typical parameter ranges used in bridges. Based on the large number of numerical calculations a design equation for interaction of shear and patch loading is proposed.Keywords steel bridge · corrugated web · patch loading · shear resistance · shear and patch loading interaction Acknowledgement This work is connected to the scientific program of the "Development of quality-oriented and harmonized R+D+I strategy and functional model at BME" project.
