Structural health monitoring system (SHM) has an essential role in the prediction of steel bridges behavior and damage detection. Due to site difficulties economic reasons, it is not possible instrumenting all sensitive details within structure. Finite element modelling effective tool for analyzing fatigue-sensitive details, as enables extension interpretation measured data. This study investigates structural Southern Railway Danube bridge located Budapest from fatigue point view. The...
The demand for welded box-sections is increasing in the construction industry due to their easy fabrication and limited stability issues compared other open sections. instabilities of box-section can be mainly categorized into three types: global buckling, local interaction buckling. Nowadays, more attention paid as designers tend use lighter sections save on weight cost. Nevertheless, there no suitable method consider nonlinear effect between which directly incorporated using FEM-based...
Current standards and specifications do not provide specific design methods to determine the lateral-torsional buckling (LTB) strength of girders with trapezoidally corrugated web. In international literature there are some previous investigations available focusing on LTB web girders. Based numerical calculations analytical solutions have been derived in past, however, is a lack experimental test results prove or improve these proposals. The authors performed an extensive research program...
The current paper studies the global and local interaction behaviour of box-section columns using numerical simulations by creating a model analysing their buckling resistances to pure compression. developed uses combination imperfections as well residual stresses, which are key parameters resistance calculation. unique approach in is that all previous applied safe sided imperfections, while this research applies improved for provided authors work. This geometric imperfection verified...
The finite element model-based design of steel structures is getting increasing attention by designers, especially in the case buckling problems welded plated and static check interacting stability behaviour. FEM-based approach introduced standardised EN 1993–1-5 Annex C providing ability to calculate resistance based on direct geometrical material non-linear analysis using imperfections (GMNIA). By this process, application (shape magnitude) has a large impact computed resistance. It true...
Before the recent reconstruction, significant corrosion damages were observed on deck system of ∼170-year-old Széchenyi Chain Bridge. Therefore, an advanced reliability analysis-based study is executed to assess risk failure structure in its situation until refurbishment starts. The current paper has aim introduce applied assessment method for analysis and damage grade determination historical structure. novel combines following techniques: (i) input data coming from on-site measurements...
There is no commonly accepted and reliable design method to determine the lateral–torsional buckling (LTB) resistance of steel trapezoidally corrugated web girders. Therefore, focus current paper on investigation this failure mode, detailed evaluation structural behavior determination accurate LTB resistance. An advanced finite element (FE) model developed validated using results laboratory test performed at Budapest University Technology Economics in 2018. Based experimental background...
