Thank you, I'll check.

Hi Gor,

thanks for your replay. I will play a little bit.

Grazie mille

Dear all,

I'm interested in looking at the analytical equations which govern the change in state of the Pinching4 material. Where I can find it?

Thanks for the attention.

Now I have a linear decrease of the amplitude, but when the restoring force is lower than the friction forces there are vibrations (with constant amplitude) instead to have a constant residual displacement. Someone can help me? Thanks Below there is an update of the code: wipe; source Units.tcl mode...

Hi all, I want to simulate the Coulomb friction between two nodes. Below you can find an example of 1DOF system with a initial displacement (1.5 m) and after that free vibration. Following theory ( see e.g. Chopra book) at each cycle the displacement should have a linear decrease, and finaly a perma...

Dear Frank,

i downloaded the latest version of OpenSeesSP 64 bit available on the website, and my operating system is windows 8.1 64 bit.

Thanks for the replay.

Dear all,

i installed all the files to use a parallel processing but when i write mpiexec -np $n OpenSeesSP $filename no action occurs. Simply i go to the next line in the command window.

What is the problem?

Thanks in advance,
Andrea

Ok, I solved in this way: set Quad quad set thick 0.18 set mat 30 if {$Quad == "enhancedQuad" } { set eleArgs "PlaneStress2D 1" } if {$Quad == "quad" } { set eleArgs "$thick PlaneStress2D $mat" } if {$Quad == "bbarQuad" } { set eleArgs "1" ...

Why if I use this sintax: set nx 16 set ny 4 set start 0. block2D $nx $ny 1 1 $Quad $eleArgs { 1 $start $start 2 40 0 3 40 10 4 0 10 } There is the following error: WARNING block2D numX? numY? startNode? startEle? eleType? eleArgs? : invalid node coordinate for node: 1 expected floating-point number...

Ok, I will wait the structural response.

Thanks,
Andrea

Thanks Dr. McKenna.

Dear all, i want to perform different nonlinear analyses on a frame structure with lots of cladding panels, so i need to perform an eigenvalue analysis. The masses are not distributed but simply concentrated on the top of the columns (5) but still the eigenvalue analysis is quite long. Is there a po...

Hi all, I want to model a precast building (in 2D) which includes beams, columns and cladding elements, for which i want to use quad elements and block2D command. However i have this error: WARNING block2D numX? numY? startNode? startEle? eleType? eleArgs? : invalid number of node args: PlaneStress ...

Many thanks.

I found that exec octave -r "FileName.m" does not work. Is there an equivalent command for Octave?

Thanks in advance
