Preprocessing: |
Three Comma-Separated Values (CSV) input files were created using MATLAB to define the problem. |
1) Bridge Data: |
Variables: (number of spans (N), and span length (L)) |
1- Set the range of N and L according to the parametric study. |
2- Loop over N and L to generate point coordinates, and frame elements. |
3- Assign frame section. |
2) Vehicle Definitions: |
Variables: (number of trucks (x), number of axles (n), spacing between axles (s), and axle load (p)) |
1- Generate load names with the following designation (Type(class)_Number(x)_Spacing(s)). |
2- Assign number of axles for each load. |
3- Define axle loads and spacing. |
4- Apply scale factor (scale factor = 1 in the current study). |
3) Load Cases: |
1- Assign lanes to frame numbers. |
2- Assign moving load cases for each load. |
The three CSV dataframes are then imported into SAP2000 |
Postprocessing using MATLAB: |
1- The results were exported in excel files. |
2- MATLAB was used to perform the analysis and generate the figures. |
