Abstract

Abstract: Currently the modernisation of railways is in progress in a large global scale. While classic ballast is verified in the long term and quite popular, the structural solutions using more quality materials (concrete, asphalt) are more and more preferred. Therefore, the slab track system (STS) was developed that is characterized as relatively maintenance-free structure of the railway superstructure where the reinforced concrete slab accepts the load distribution function of the ballast [1-4]. In the case of bridge structures, the slab tracks are built mainly on concrete bridges where the rigid connection between the STS and the bridge deck is solved using the cross-shaped slab directly concreted on the bridge deck. Application of STS on steel bridges is rarer and therefore the design is not entirely clear. Therefore, the main purpose of this work is to analyse the possibilities of utilizations of STS on steel bridges.
