Abstract Composite steel concrete bridges with embedded continuous shear connectors are one of the newer popular options for short span (up to 20 m) bridges. They can be used for both road and railway bridges and due to their low structural height, nowadays, they are also a welcome alternative for bridge reconstructions – the concrete part serves as the bridge deck as well as the main structure. Unfortunately, In the Slovak Republic, no such bridges have been built as of yet (2020). At Technical University of Kosice, Department of Steel and Timber Structures, an extensive research regarding the steel shear connectors have been launched. Its goals are to bring new, easier for construction (due to prefabrication process), more resistant with even lower structural height, and more economical (due to lesser usage of materials and quick construction) geometrical solutions for composite steel concrete bridges as well as to open and popularize this solution for developers in the Slovak Republic. In this article, one of the new types is presented. It has a cross-section in a shape of a trapezoid, with holes in all its sides, except the bottom flange. Their purpose is to create concrete studs and secure full shear transmission with higher shear resistance, but they also serve to create space for transverse reinforcing bars. Its geometrical and material characteristics are closely specified. Results and process of push-out tests performed in Laboratory of Excellent Research onto three specimens are described and compared to results of finite element analysis simulation performed in Abaqus software.

Abstract Continuous shear connectors in a shape of dowels are one of the newer shapes of composite steel-concrete bridges. In this article results of push-out tests of such a dowel with geometry designed at Faculty of Civil Engineering, Technical University of Kosice are presented and compared to the previous research.

Abstract Different types of shear connectors and modelling techniques are presented. Basic research conducted or presented after year 2000 is taken into consideration, following the idea of concrete dowel implemented in the form of perfobond strip at the beginning of the 1980s by F. Leonhardt. The latest research in the field of continuous shear connectors applied in bridges is highlited with special focus at the composite dowel shear connection, as it seems to be the most modern solution being strongly introduced to the industry. Final shape of composite dowel shear connection is presented.

<p>Composite bridges with encased steel beams, or nowadays, rather encased steel continuous shear connectors are a welcome option for short span railway or road bridges. With lower construction height and easy construction of prefabricated composite beams it brings a new, complex, solution for replacement of older, overserved bridges, as well as for new tasks. At Technical University of Košice, Faculty of Civil Engineering a new designed of the steel perforated strip was developed. At Laboratory of Excellent Research several experiments for resistance finding were carried together with material tests. In this article the numerical analysis of push-out tests performed is closely described and the shear resistance of finite element model developed in Abaqus/CAE is compared to experimental results.</p>

The use of prefabricated elements and systems in bridge construction has recently been the subject of much attention and interest amongst bridge jurisdictions as a way of improving bridge construction. Through mass production of the materials, the repeated use of forms, reduction of on-site construction time and labour by concentrating the construction effort in a fabrication facility rather than at the bridge site, significant economic benefits can replacement. The current traditional bridge rehabilitation/replacement system in most situation is very time consuming and costly. Issues related to work zone safety and traffic highways because of the significant economic impact on commercial and industrial activities. As a result, prefabricated bridge technology is seen as a potential solution to many if these issues. Prefabricated elements and systems can be quickly assembled and could reduce design efforts, reduce the impact on the environment in the vicinity of the site, and minimize the delays and lane closure time and inconvenience to the traveling public, saving time and tax payers' money. This project investigates the full-depth precast bridge deck panels with no overlays connected to the steel girders using lumped shear connectors Eight panel-steel girder connections of different shear connector configurations were erected and tested to complete collapse to examine their structural behaviour, crack pattern and ultimate load carrying capacity. Based on the experimental findings, recommendations for practical applications were drawn.
