Matrix Structural Analysis


Hossein Rahami (view profile)


A simple function for the analysis of two- and three- dimensional frame structures

File Information

The stiffness method is used for matrix analysis of structures. this program is useful for analysis of Planar trusses, Space
trusses, Beams, Planar frames and Space frames.
End release of members in frame elements and support displacements can also be applied by this program.


This file inspired London Kings Cross Western Concourse Genetic Algorithm and Truss Simulation.

MATLAB release MATLAB 7.4 (R2007a)

Hi Javier Saez

Column 3 and Column 4 of D.con are used for start and end point of any element. If start point of element is fixed, you input "1", if this element has a release in this point,you input "0". For truss systems, D.con Column 3 and 4 are "0" but for frame systems, they must be "1" (if element doesn't have any release"

Thank you so much. I've a question about program Data.m. Can anyone tell me what's the meaning of columns 3 and 4 of the D.Con' matrix?

Thanku so much sir.I have written a code but not as simple and generalised as yours.

من دو روزه کل اینترنت رو زیر و رو کردم و انواع توابع و اسکرپیت های ماتریس سختی رو دیدم ، واقعا این چیزی که شما نوشتید یه چیز دیگه است .
و البته حالا که متوجه شدم شما ایرانی هستید اصلا یه جور دیگه واسه ام لذت بخشه .
آفرین .
ممنون از اشتراک این فایل

Do you use SI units? Else what are the units? Thanks

Dear Dr.Rahami,

Thank you so much, I'm trying to add the modal analysis to this code, please can you tell me what would happen to the mass matrix of the element when we release member ends?
