Article
The most widely used shear connector of steel‐concrete composite beams is the well‐known headed stud and it can be used for innovative bridge girders with trapezoidal webs embedded in concrete slab as well by horizontally placing the studs on the embedded steel part. Another option for trapezoidal web girders is the closed or open cuts on the corru...
Article
The application of steel trapezoidal corrugated web in steel-concrete composite girders has been widespread in building structures and has also appeared in bridges for a few decades, due to their advantageous mechanical properties. Embedding the trapezoidal web in the concrete slab leads to additional advantages such as omitting the welds of the to...
Article
The application of trapezoidal corrugated plate as the web for girders, thanks to a number of favorable features, modernizes the manufacture of steel-concrete composite and hybrid structures and provides an alternative, competitive structure for small, medium and large span beams. However, the traditional headed stud shear connectors on the top fla...

Traditionally in steel‐concrete composite bridges, the structural elements with different materials are work together with headed stud shear connectors welded to the top flange of the steel beam. The application of trapezoidal corrugated web embedded in the concrete slab provides an alternative for steel‐concrete composite and hybrid structures, ho...
Conference Paper
Hybrid girders with corrugated web are increasingly used in bridge engineering due to its numerous favorable properties. For the web-to-slab connection different layouts have been developed in the past, however, just a few design proposals can be found in the international literature for the determination of the connection’s resistance, especially...
Article
Full scale tests on eight steel‐concrete composite beams have been executed in the Structural Laboratory of the Department of Structural Engineering, Budapest University of Technology and Economics in Hungary. The aim of the test series was to investigate the structural behavior of the new and innovative shear connections applied at the steel‐concr...

In frame of the tramway network development in Budapest a new tramway line has been established on the south part of Budapest, which crosses the Danube on the Rákóczi-bridge. The bridge superstructure is a continuous double-cell steel box girder having 6 spans with the largest span of 98.52 m. The bridge was originally designed to carry four traffi...

Climate change affects not only the natural but also the built environment. The latter comprises large part of societal wealth, and it is a crucial component of developed economies. The focus of this paper is the quantitative assessment of the reliability of load bearing structures in changing climate. Despite its significance, relatively few quant...
Conference Paper
Full-text available
This paper examines the reliability level of post-elastic ultimate limit states for steel-concrete composite bridges. This is motivated by the benefits of exploiting the inelastic reserves of composite bridges which allow for more economic design of new structures and the extension of the service life of aging, deficient bridges [1]. Although the E...

Due to mainly human activity in the following decades we are facing increasing mean global temperature and rising CO 2 concentration. This paper investigates the effect of these changing environmental parameters on the durability of concrete structures. We restrict our attention to the examination of carbonation process and to environmental data ap...
Conference Paper
Full-text available
The costs related to corrosion are immense and they are expected to rise in the following decades due to human induced climate change. This paper examines a slice of this problem: the carbonation process-which is the most common corrosion type of concrete structures-in the light of climate change. Since current durability specifications are prevale...
Conference Paper
Full-text available
The management of aging, decaying bridges and construction of new ones, due to growing traffic, impose great burden on society and economy. The exploitation of – in current design practice generally neglected – post-elastic reserves of composite bridges could effectively tackle these issues. This paper investigates the plastic reserves of two span,...
Conference Paper
Full-text available
Contrary to the previous design practice-which is overwhelmingly based on elasticity-the new European standard allows the mobilization of plastic reserves of composite bridges. Hitherto, no comprehensive study was made to assess the achievable gain through the exploitation of these reserves. This paper makes an attempt to fill this gap for composit...
Article
The subject of this paper is the analysis of end-plate joints under cyclic and monotonic loading conditions by experimental and analytical studies. The experimental programs are performed on bolted end-plate type joints of composite members under cyclic loading conditions with the purpose to study the seismic response of the considered connection t...
Article
In this paper, an experimental program on bolted end-plate type column-base joints is reported. Composite base columns are investigated under cyclic loading to study and characterise the typical cyclic behaviour modes of these types of joints. Details of the specimens, test results and the evaluated experimental data of the tests are presented. The...
