STAAD & SDNF Files
You may import or open STAAD (.std) script files as an entirely new project, also known as command language files. To open a STAAD file you may use, or for better diagnostic information, create a new empty project and then use .
The SDNF (Steel Detailing Neutral File, .dat) version 3.0 may also be read or written with Steel projects.
The purpose of this feature is to allow easy data transfer of basic model and load information among different structural analysis products. STAAD has been around a long time and many programs offer STAAD import/export abilities. This command is not designed to read every .std file or support every feature of this command language. You may need to modify your .std file in order for VisualAnalysis to read it successfully.
Many STAAD commands are not supported either for import or export. While many of these commands are 'accessories' to the core model and load data, some may impede your ability to import the data you need. You will very-likely need to edit a STAAD file to remove commands before VisualAnalysis will import the file successfully! The purpose of this tool is to ALLOW importing STAAD data, not necessarily to make it automatic.
Supported STAAD Features
The following commands may be imported:
STAAD (PLANE, SPACE, TRUSS)
MEMBER PROPERTY (Prismatic and database shapes should work, names must match exactly the VA shapes)
ELEMENT PROPERTY (THICKNESS)
MEMBER LOAD (UNI, CON, TRAP)
ELEMENT LOAD PRESSURE (Local only)
Allows export of the basic model and loads from VisualAnalysis models into these formats.
VisualAnalysis provides advanced parsing of the STAAD input file to indicate where problems are so that you can manually edit the file to correct the situation. The line number of the error is shown in context to help you find problems quickly.
If you import using themenu, you will get additional diagnostic information if there were any problems or issues.
- IES continues to work on the import/export of STAAD files and so this documentation may be slightly out of date! Patience, and "trial & error" may be your best approach to working with the import of files in this format...please keep us posted if you have problems or issues you would like us to resolve. IES does not own the STAAD file format, and we have no control over its evolution, and very little historical knowledge!
- Some of the specific, and perhaps more common,
unsupported commands that will break your STAAD file include these:
CONSTANT [use DEFINE MATERIAL and ISOTROPIC instead]
- Other STAAD commands are simply ignored during parsing, they will not
break your file but have no effect in VisualAnalysis, including these:
- Not all VisualAnalysis features will be exported to either format. The goal is to export the basic model definition and loads and load combinations. Advanced or design features, will not be exported.
- The purpose of this tool is to provide a good starting point and files may require some manual editing.
