The problem of transition zone of structural steel element connected to concrete is discussed in the following paper. This zone may be located for instance in specific bridge composite girder. In such case the composite beam passes smoothly into concrete beam. Because of several dowels usage in the transition zone, the problem of uneven force distribution were discussed through analogy to bolted and welded connections. The authors present innovative solution of transition zone and discuss the results, with emphasis put on the transition zone structural response in term of bending capacity, failure model and force distribution on the connection length. The article wider the already executed experimental test and presents its newest results.

“…It was the motivation to analyse the similarities and differences between PBL and CD. Appropriate research was carried out as part of a doctoral dissertation [15] where the most important selected design approaches used in various countries for the description of PBL and then CDs were analysed. In particular, the Japanese experience was taken into account as PBL is widely used there (Fig.…”

The introduction of composite dowels (CDs) in Europe at the beginning of the last decade led to the creation of new forms of composite bridges in which a T‐profile is used instead of an I‐beam. Both the construction and design methods are new [4]. Experiences from the construction of new bridges and discussion between the authors lead to new significant conclusions, which should be included in the new European approval (CEN‐TS). The problem of design formulas for concrete dowels is presented.

“…Anchoring structural steel in concrete is a complex issue that requires the solution of several problems. These include the selection of the type of connector, the determination of the load-bearing capacity of a single connector [8] and of a group of connectors [5], and the solution to the problem of structural steel pulling out of the concrete in the transition zone [6]. It should be also noted that the solution is dependent on the other parts of the whole element, must be consistent and do not change it significantly.…”

New Type of Transition Zone for Steel‐concrete Hybrid Beams in Bridges

et al. 2023

A new kind of composite connection is implemented in bridge engineering in Poland, which leads to a new type of steel‐concrete beams. First innovative bridges are constructed based on in‐depth scientific works. Perfobond shear connector (PBL) concept has been combined with standard geometries of composite dowels and in this way, efficient shear connection has been created that is used in combination with composite dowels. It enables a new type of beams that have more general forms than standard composite beams – they are named hybrid beams. There are intensive R&D works going on towards optimization of the transition zone concept. The article widens the already executed experimental tests, summarises the development of the hybrid beams, and presents the application of the hybrid beams in bridges.
