Dear forum members,
Do you know if it is possible to perform the Hilbert transform of simple function, say, f(t)=sin(t) in Matlab?
Thanks so much..

Dear members,
Is it possible, while drawing figures, to add a legend
direclty onto the lines of a figure instead of having a seperate legend box.
In other words, consider the following as curves/lines in a plot, is it possible to do
-------P=2--------
.......P=3.......
_______p=4_______
and...
Thank you guys for your replies,
But I was just wondering about the ratio of the axial load present at that column (not the capacity of the column) to its buckling load.
Thanks so much for your input :)
Dear friends,
How can I determine the transverse natural frequencies of simply supported beam under an axial compressive loading?
When I apply the loading at supports, no changes in the freqeuncies occur beacuse, I guess, the beam does not feel it is under axial loading. Specifcally, how can I...
Dear forum members,
I would like to know the level of axial load of a column (or beam) in a concrete or steel frame at service conditions as a percentage of buckling load.(1%, 10%, 50% or what?) Any body has an idea?
Pls help. Thanks very much.
Luke
dear zer,
thanks for your help but I know of that movie,
it does not give any details of the analysis procedure.
what I d like to learn are the essence of the Pushover
and how you d perform for a simple RC structure, issues
related with modeling the steel bars in the elements etc.
Any...
dear feadude,
I am looking for college (undergrad or grad) FE course notes.
dear TSG4 and GBor
http://ocw.mit.edu/index.html did not work for me, as no course on FE there. There is a similar course but the course notes are taken by handwriting-namelly, hard to read & understand.
Plz let me...
Dear forum members,
I would like to model a local flexibility, caused by a crack
on a beam, through a rotational spring. The spring has stiffness
about Z axis only, the spring assumed to be fixed at other directions.
To model this spring, what kind of element should I use? and
what...
Dear Drej,
The analytical work I have been doing is to drive the equation of motion of a Timosheko beam governing the transverse osccillation of the beam. Then imposing the initial conditions (support conditons), I try to find the modal response (frequencies, mode shapes etc.)
I need to...
Dear Drej,
I have been investigating the effects of shear def. and rotational inertia on the frequencies of a beam, that s why I need to use Timoshenko beam.
I did some analytical work and got the results. However, the results seem incorrect and need to compare them with true/actual values.
I...
Dear Claudio or drej,
Thanks so much for your reply but I could not really understand this Ansys and have not been able to find the frequencies of a simple Timoshenko beam. I am also trying to find them by hand but the results
are contradictory. I am realy desperate.
Would you please find...
