GS. STAAD Input Files

A STAAD model consists of a data file made up of simple, English-language like commands, using a format native to STAAD.Pro. This file specifies all input, analysis, and output commands used to inform the STAAD engine as to the geometry of the structural model, loads acting on this model, and instructs the engine on the analysis and design operations to be performed.

There are two methods for building a model and assigning the structure data using STAAD.Pro:

using the graphical model generation, or
directly editing the command input file using the STAAD.Pro Editor

The graphical method of creation (a) involves using either the Analytical Modeling or Physical Modeling workflow to draw the model using the graphical tools, and assigning data such as properties, material constants, loads, etc., using the various tools and dialog boxes of that mode. In this approach, the command file is automatically created by the program while you work. The input command file is updated whenever your structure is saved.

The direct editing method (b) involves creating or editing the command input file (file extension .std) directly using the STAAD Editor utility. These commands are explained in detail in Technical Reference of STAAD Commands and several examples which illustrate this method are provided in the Application Examples.

Tip: The command input file is a plain text file so you can use any plain text editing software you prefer. However, it is recommended you use the STAAD.Pro Editor as this program contains tools such as Intellisense to complete commands and syntax checking.

Tip: For a hands on illustration of both these methods, it is recommend that you take a look at the Tutorials.

Regardless of the means used to create the STAAD input file, once the model is ready for analysis, you will use the graphical environment to initiate analysis, review the analysis and/or design output data, and perform advanced design operations.
