hi
i'm performing some modal analysis in a 3D model.
i'm having the following message:
ProfileSPDLinDirectSolver::solve() - aii < 0 <i, aii):(1372, 0)

do you know what this is ?
thanks in advanced
Hugo

I’d like to know if there any problem in mixing forced-based-elements with displacement-based-elements ?
In particular case mixing nonlinearBeamColumn to model a column and the zeroLengthSection to model the bond slip.
Best regards.

Strange. I run your code with OS Version 2.0.0 and got no convergence error!
OS results:


d: 1.8
fy:35000
E:20000000
eps:0.00173
Estimated yield curvature: 0.00137301587302

thanks.!

I’d like to know the time duration in seconds on an analysis.
There is any OS command or TCL command to know this?
Tanks in advanced.

I’m trying to use it really.
But I can’t understand how to define a new geometry.
It’s possible to define a new geometry.
I read briefly the manuals but I can’t find that.

see the file: myBuildingTcl.tcl on the folder BuildingTclDemoFiles

I can’t find it also. But the complete error is: couldn't read file "C:/Users/AASilvia/AAProjects/OpenSees/BuildingTcl_All/BuildingTcl_Release1.5/BuildingTclProgramFiles/LibBuildingTclLibraryFiles.tcl": no such file or directory couldn't read file "C:/Users/AASilvia/AAProjects/OpenSee...

Very good. I will use it. I have already installed. But I can’t run the examples. Give me some erros … When I try to load models3D.tcl Gives me: “can read “Floor” When I try to load: BuildingTclFrame3D.tcl Cant find: “C:/Users/AASilvia/AAProjects/OpenSees/BuildingTcl_All/BuildingTcl_Release1.5/Build...

I’m doing biaxial analysis of RC columns also, and I use the to run SP command to load the discplacement history and works fine with me #recorder plot BaseShearx.out PushICurvex 100 100 400 400 -columns 2 1 set SeriesPath1 "Path Series -dt 1 -filePath path1x.txt" set SeriesPath2 "Path...

Silvia,

The BuildingTcl is very good.
I’d like to know if for 3D buildings there is anything coming ?

Hi hrodrigues; i have encountered the some question. When i use opensees1.7.3,the "sections" work well, but not work using opensees 2.0 version. how did you solve it? It Works in OS 2.0 Please see the example: element nonlinearBeamColumn 101 51 11 3 UserDefined $numSec 111 112 113 112 111...

ok!
no problems now ...

thank you!!

Silvia, the ActiveTcl 8.5.5.0 for Windows is already available i install it and it works. http://www.activestate.com/store/download.aspx?prdGUID=f0cd6399-fefb-466e-ba17-220dcd6f4078 the 8.5 version is not available in the OS downloads. one more question .. the OpenSeeS.exe 2.0.0 have 5.21MB and the ...
