Abstract: Application of the corrugated web girders has been widely spread due to their numerous advantages in the field of bridges and buildings in the civil engineering praxis. This girder type has a special stress distribution and buckling behavior compared to conventional steel I-girders. Despite, there are a relative small number of previous investigations dealing with the bending moment and the flange buckling resistance of the trapezoidally corrugated web girders. Previous experimental and numerical investigations confirmed that the bending moment resistance according to the EN1993-1-5 often results in unsafe resistances if the compressed flange belongs to cross-section class 4. Therefore, improved design models are developed by different researchers in the past, but there are contradictions in the previous design models regarding the consideration of the flange width and the clamping effect of the web. The current paper collects all the previous research results on the flange buckling resistance and introduces an additional experimental research program investigating the flange buckling behavior and the bending moment capacity. The companion paper (Part II) [1] introduces the executed numerical research program and the design method development for the flange buckling resistance.

TL;DR: In this paper, the lateral-torsional buckling (LTB) of hybrid corrugated web girders (CWGs) built up from flanges with a yield stress of 690 MPa, which has been used in bridge construction worldwide, was investigated.
Abstract: This paper is devoted to investigate the lateral-torsional buckling (LTB) of hybrid corrugated web girders (CWGs) built up from flanges with a yield stress of 690 MPa, which has been used in bridge construction worldwide. The hybrid girders have been utilised to provide a cost-effective solution because of the high material cost of S690. This investigation has been based on the finite element (FE) modelling by using ABAQUS program. Accordingly, material modelling of S690 has been verified by considering recent experimental tests in the literature. Then, the accuracy of the current FE models of the CWGs has additionally been checked successfully. Parametric study has been carried out on simply-supported girders, for bridge construction, considering mainly the influences of the hybrid ratio and corrugation dimensions on the behaviour of the CWGs built up from HSSs. A limiting slenderness ratio for the inelastic LTB of 2.3 has been found, where more slender girders would not benefit from using such HSS material. Additionally, the strengths of the girders have been compared with EC3 design model, which has been found to provide highly conservative predictions for the current girders. Consequently, a new design model has been suggested. This suggested bending strength is generally found to provide accurate predictions for the hybrid CWGs built up from flanges of S690 HSS; especially for girders failing inelastically. Finally, several comparisons have been provided that might aid the structural engineers in designing efficient hybrid cross-sections in the future.
