Abstract
Until recently, steel plate girders with corrugated steel members were used primarily as poles and girders in the construction of industrial buildings. Currently, they are also being used in the construction of bridges. Compared to traditional steel and rolled girders, steel plate girders weigh less and are more stiff, while also having a neater appearance. In this paper, the results of an experimental study are present. The aim of the study was to determine the behavior of a bridge girder with sinusoidal web geometry when subjected to a bending moment. The study was focused on a composite steel and concrete structure with pin connections, which is currently the most common solution. Three near-real scale beams were subjected to bending tests. The study found that composite corrugated-web steel beams and non-composite corrugated-web steel beams showed similar forms of failure. A reinforced concrete slab did not prevent web stress concentration at the point of connection with the flange. Furthermore, the study indicates that corrugated steel webs in bridge girders can have a much smaller thickness (less than 8 mm) compared with the traditional solution.
Highlights
Composite structures are unique in that they consist of diverse materials, and that these materials are located in specific section zones to make the best use of their stress-strain properties
In composite steel–concrete decks, individual cross-sectional components are made of materials with different
Across all loads in composite beams, there were no deformations in the steel part of the plate
Summary
Composite structures are unique in that they consist of diverse materials, and that these materials are located in specific section zones to make the best use of their stress-strain properties. Researchers are looking for new structural solutions to meet increasingly strict economic and operational criteria, while adhering to the requirements of standards (including for both the ultimate limit state and serviceability limit states) [8] These efforts have led to the emergence of a solution using corrugated-steel webs for composite, primarily steel, bridges [9,10,11,12]. Until recently, corrugated-web steel beams were used mainly as structural components of buildings, in particular as poles and girders in industrial buildings [13] They compete with traditional steel girders and rolled profiles, mainly because of their lower weight and higher stiffness [14]. They give the structure a neater appearance [11]
