non-linearity, masonry, arch bridge, load carrying capacity


This article focuses on masonry arch railway bridges. The main topic is the algorithm, which was developed for the purpose of a non-linear arch bridge analysis. The sensitivity analysis of the input parameters of the calculation was carried out. Subsequently, the study was carried out for the comparison of four calculation methods. For this comparison, a set of arch bridges were chosen. Two methods used commercial software, and the other two methods were developed. One of the developed algorithms uses a simple linear calculation. The second developed algorithm uses an iterative approach to handle material and geometrical non-linearity. The first commercial software method uses 2D non-linear models, the second method is a limit collapse analysis using the software LimitState:RING. These three methods were developed to handle the SLS (serviceability limit state) criteria, and their results were compared to the result of LCC at the ULS (ultimate LS) using LimitState:RING.
