STAAD PRO 2004 SOFTWARE
STAAD is a comprehensive structural engineeringsoftware that addresses all aspects of structuralengineering analysis, design, verification, and
visualization.
STAAD performs the analysis and design of thestructure for different types of structures, such as
trusses, plane, space (3D), floors (2 D plane and butloads 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 graphicalmethods.
Further readings and more information about theprogram can be found through the internet.For example www.reiworld.com

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 acantilever part its span equals 4.0m. The proposed truss depth is3.0m.The loads as shown, are concentrated at the truss joints. Thevalues 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 Define the Truss Geometry?One of the methods that you can createconstruction lines and then draw onthese lines the truss members.
Noting that the number ofconstruction lines is excludingfirst line.

4. Defining Loads
The creation andassignment 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.

Also, we can define load combinations according to required.

For example, we can create a load combination1.25 D.L. + 1.5 L.L + 0.8 W.L.
