Combined shear and patch loading of girders with corrugated webs

Abstract

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.

Behaviour of corroded steel angle compression members – numerical study

“…In the ANSYS [15] finite element software environment a 4-node shell element (SHELL 181) is applied, which can model thin and moderately thick plated structures and it is well-suited for large strain nonlinear applications. Note that this finite element was applied in Liu's numerical study [12] of non-corroded angle elements under compression and by Kövesdi et al [16] to investigate stability problems of steel girders with trapezoidal webs. In case of shell models the different continuously rough surface cannot be modelled accurately if the corrosion is different on the two sides of the legs.…”

Stability behaviour of sinusoidal corrugated web girders under fire conditions

“…For instance, Pasternak and Kubieniec [8] concluded that the buckling resistance of typical sinusoidal corrugated web girders with a web thickness of 1.5 to 3 mm are comparable with conventional girders manufactured with 12 mm thick flat webs. Recently, a number of experiments dealing with the particular behaviour of this girder type have been carried out at room temperature [9][10][11][12]; in addition, Annex D of EN 1993-1-5 [13] deals with design rules for girders with corrugated webs at room temperatures. On the other hand, structural behaviour of corrugated web girders at elevated temperature has not been widely analysed [14][15][16] and requires further investigation and clarification.…”
