- As a post-processing feature, Rail Track Analysis Report could be used to analyze all the models and obtain the compiled excel file. It provides the final summary sheet with checks based on UIC 774 - 3. These check limits could be manually modified for regional codes. This report wizard could only be used with Simplified Separate Analysis option. Complete Analysis Model is not supported for the report. The report will contain tabulated data as well as graphical output for individual rail stresses, rail and deck relative displacements as well as deck absolute displacements.
Automatic Generation of Individual Analysis (Simplified Separate Analysis) Modeling
Case 1 : Temperature load case model without train load
Case 2 : When train load is applied, traction/bracking load and train vertical load case model which has different ballast resistance for both loaded and unloaded section.
Automatic Generation of Step-by-Step Analysis (Stage Analysis or Complete Analysis) Model
Unloaded stage : Unloaded Condition as a stage in which only temperature load is applied, and the ballast resistance is uniformly distributed throughout the entire span.
Loaded stage : Loaded Condition as a stage that includes traction/bracking load and vertical train load, where the ballast resistance is applied only to the section where the train is present.
Automatic Generation of Moving Load Analysis Model
In the second stage of Stage Analysis or Complete Analysis, the train load is applied to different segments of the bridge to determine the location where maximum additional stress is induced. The analysis is performed by changing the train segment by a fixed length and generating step-by-step model files that incorporate the changing boundary conditions.
Auto-generation modeling analysis and report
Each generated model is automatically analyzed, and based on the analysis results, a review report is generated.
The automatically generated modeling cases are stored within a folder named after the file name before generation.
