Analysis of bow‐string arch using geometric data from 3D scanning
The utilization of currently measured geometric data for analysis of arch bridges and their stability is discussed. The presented contribution follows a set of research activities focused on real values of geometric imperfections of a steel bow‐string arch bridge using 3D scanning. Relatively new railway arch bridge with span 124.8 m is discussed. Deviations from the theoretical design shape of the arch were recorded during the erection stage and after a proof‐load test of the bridge, as well. Thus, it was possible to observe if and how the geometric imperfection changes during construction. Numerical models were created to perform geometrically nonlinear analysis. Both theoretical and real imperfections obtained by 3D scanning were considered in the analysis to compare and quantify the influence of the actual deformed shape. Finally, the obtained data, their comparison, the applicability of the presented methods, and possible pitfalls of the procedure are discussed.
