ENGI 7704 Design of Steel
Computer Analysis of Steel
Structures by STAAD
STAAD PRO 2004 SOFTWARE
STAAD is a comprehensive structural engineering
software that addresses all aspects of structural
engineering – analysis, design, verification, and
STAAD performs the analysis and design of the
structure for different types of structures, such as
trusses, plane, space (3D), floors (2 D plane and but
loads are vertical or out of that plane).
Giving demonstration for how to use the software by
showing only the basic steps for static analysis.
As STAAD has two main methods of modeling
(input editor (script language) and/or through graphical
environment). Tutorials will show only graphical
Further readings and more information about the
program can be found through the internet.

STAAD Tutorial No.1
ANALYSIS & DESIGN OF STEEL TRUSS
TUTORIAL NO.1: STEEL TRUSS
The figure above shows a steel truss from several trusses
supposed to cover a certain area. As shown, the truss has a
cantilever part its span equals 4.0m. The proposed truss depth is
3.0m.The loads as shown, are concentrated at the truss joints. The
values of its load case are shown. Use all the data you take in the
Steel Course for analysis and design.
Main Steps of Modeling
Entering job information.
Building model geometry.
Defining member properties, sections.
Assigning loads (load cases, combinations..)
Defining pre-analysis print out, analysis type,
and post-analysis printout.
Defining design requirements.
How to Start the Program?
From Start Menu - Select the STAAD.Pro icon from the
STAAD.Pro 2004 program group.
The STAAD Graphical Environment will be invoked and the
following screen will appear:
1. ENTERING JOB INFORMATION.
2. Building Model (Structure) Geometry
How to Define the Truss Geometry?
One of the methods that you can create
construction lines and then draw on
these lines the truss members.
Noting that the numbe
