If you get any error messages, you can edit your input by hitting the STAAD Editor IF you made any mistakes in your input, you will be informed! Hit the Done button.ħ. The next screen should look like the following.
You will then see the following:īe sure to pick STAAD Analysis and then hit the Run Analysis button Select Analyze (see above) and pick Run Analysis. You are now ready to analyze the structure you just created. Joint 1 coordinates 0,0 Joint 2 coordinates 10,8 Joint 3Ħ. Load of -9000 lb in the Y direction at Joint 4 (minus = downward force)
Member 1 is between Joints 1 & 2 Member 2 is between Joints 2 & 3 Member 3 YD = Depth in Y direction = 3.5 ZD = Width in Z direction = 1.5 The following screen will appear: (See next page) When finished inputting the information EXACTLY as shown above, click the X (close) button. The easiest way to do this is by picking the STAAD Editor icon (see above) and input information EXACTLY as shown below:
First, you must SAVE your work by clicking on the Save icon. Save your work by clicking on the Save icon. You are now in the main graphic environment of the program, and the screen willīe sure to click Foot and Pound, then pick Next.ĥ. The next screen will look like the following:Īnother screen will appear, pick Finish. Pick the New Structure icon (or, go to File New) and the following will appear:īe sure to click Truss and put in a title as shown here. This will open the program and will look like:Ģ.

Tension 1714 PSI To begin the analysis, a computer model of the truss must be determined, and joints must be defined (in X,Y coordinates) and members must be assigned as follows: Member No. STAAD Truss Analysis Example: The following simple truss will be analyzed using STAAD: By hand-calculations, it was determined that the forces in the members are as follows: Member: Force: Tension or Compression: Stress: AB and BC 7203 lbs. It is capable of analyzing the largest 3-dimensional projects such as skyscrapers, stadiums, etc., or simple beams, trusses, or any other structural member or system. STAAD is an acronym for STructural Analysis and Design, and was introduced in the early 1980s.
STAAD PRO ANALYSIS EXAMPLE SOFTWARE
STAAD Computer Software: STAAD Pro is one of many commercially available general-purpose structural analysis/design software packages. Basics of Computer Structural Analysis: All computer based structural analysis programs work in a similar manner the structure is broken into individual joints and members and Hookes law is used to determine forces, stresses, deflections and moments from large matrices of the load interactions between the joints and members. Over the years, software was further developed and refined for usage by structural engineers to include analysis of structural elements as well as design of these members. Originally, computer structural analysis was developed by mechanical and aerospace engineers for the airplane industry to calculate stresses on the wings and fuselage. Prior to the advent of digital computers in the 1960s, the analysis of these structures was most likely performed by approximate methods (such as moment distribution and portal analysis), or more rigorous exact methods involving applications of matrix and differential math. The real world, however, is much more complex and is composed of structures having multiple stories and supports, trusses, space frames, flat plates, arches, etc. Lecture 20 Computer Structural Analysis using STAAD BACKGROUND: Structural analysis by hand methods is feasible only for relatively simple structural members such as simply-supported beams and other 2-dimensional statically determinate frames.
