“…The basic model with straight webs is verified with a comparison of previous research on the same bridge. De Backer et al (2014) used the Schaarbeek bridge in order to find the critical normal force that leads to out-of-plane buckling of the arch. However, the bridge was modelled in detail; it is possible to compare the results.…”

A bridge is nowadays more than a structure that connects people over an obstacle. When a bridge has to be built in an urban area, either it has to be a landmark or it should blend away in the environment. The use of curved steel panels is one option to obtain these requirements. However, due to a lack of knowledge, engineers end up with a conservative design to implement these structural elements. For that reason, a Finite Element Model is made of a railway bridge, where the outer webs of the main girders have a varying web curvature. Six different models are made and compared. The most important parameters that are compared are the deformations and the stresses in the webs. The study finds that curved webs have an equal or even better behavior than flat webs, even with smaller web thickness. This makes that designers can use curved webs in their design, without needing extra steel to make their design safe.

in the papers of the authors of present work. Results of the numerical-analytical variant of the boundary element method are distinguished by high accuracy and reliability.The scientific literature typically reports solutions to SDS of circular arches, obtained by known methods. It is rather difficult, however, to estimate accuracy of the obtained results and their reliability. Given this, a task of applying BEM to the calculation of SDS of circular arches is relevant for the following reasons:1. There appears a possibility to obtain accurate results for SDS of arches at different loads and boundary conditions of support, which is problematic when employing the known methods of structural mechanics.2. It is necessary to make sure that BEM actually allows obtaining accurate results for the calculation of SDS.3. It is extremely useful to have resolving equations for the boundary value problems of flat deformation of circular arches under various supporting conditions. IntroductionRods in the shape of an arc of a circle (circular arches) are widely used in construction and industrial machine-building, particularly, in crane building when designing specialized cranes. Their application is predetermined by advantages in comparison with the structures that consist of straight rods, given the higher load-bearing capacity and rigidity [1]. In the present study, in order to calculate circular arches, we applied a numerical-analytical variant of the boundary element method. The use of this method is predetermined by advantages over the existing methods of structural mechanics. In particular, the methods of force, displacements, initial parameters, finite elements and others do not have the possibility to accurately account for the concentrated moment in the form of external load and exact solution to a problem on the planar deformation of a circular arch.
