ENGI 7704 Design of Steel Structures Computer Analysis of Steel Structures by STAAD Prepared by Shah Alam 1
STAAD PRO 2004 SOFTWARE STAAD is a comprehensive structural engineering software that addresses all aspects of structural engineering – analysis, design, verification, and visualization. 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).

STAAD Tutorials 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 methods. Further readings and more information about the program can be found through the internet. For example www.reiworld.com 3
STAAD Tutorial No.1 ANALYSIS & DESIGN OF STEEL TRUSS
4
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. 5
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:
10
1. ENTERING JOB INFORMATION.
11
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 number of construction lines is excluding first line.

14
How to see the Diagram Labels (ex. Node numbers, beam numbers, etc.?
15
Node and beam labels are a way of identifying the entities we have drawn on the screen, and very useful when dealing with the output results.
16
3. Defining member properties, sections Property: In which we can define or choose sections properties of the members of the truss. Spec.: In which we can define or choose members’ specifications. Support: In which we can define the supports properties (restraints). Load: In which we can define the applied loads, load cases, load combinations. Material In which we can define the material properties. (ex. E, density, etc.) 17
Property:

19
Assigning the sections created to the model
20
Supports
By clicking on the support icon the shown window will appear. We have to create new kinds of supports.

4. Defining Loads The creation and assignment of load cases involves the following two steps: 1. First, we will be creating all 3-load cases. 2. Then, we will be assigning them to the respective members/nodes.
25
26
27
Also, we can define load combinations according to required. For example, we can create a load combination 1.25 D.L. + 1.5 L.L + 0.8 W.L.
