"tangentDrift" recorder of forcedBeamColumn element

Does anybody know what are the outputs of "tangentDrift" recorder for a forcedBeamColumn element? It has two columns of data. I looked at the -xml file format but Response Types are not specified there. Looking at Figure 1 of this paper: "Model for Cyclic Inelastic Buckling of Steel B...

Geometric transformation for zero-length elements

Hi, When a zero-length element is defined there is an option named: -orient $x1 $x2 $x3 $yp1 $yp2 $yp3 which takes care of axial orientation of the element (as the length is zero) as well as other two local axes. Now my question is: does a zero length element handles large deformations? (like the wa...

Re: Running OpenSees files from Notepad++

You can create a batch file if you want to run your model several times. In order to create a batch file, create a txt file with ".bat" extension and copy this in it: echo off cls echo Starting OpenSees.. echo off location_of_OpenSEES\openSees.exe location_of_your_model\yourModel.tcl and t...

Re: rayleigh damping recorder

Yes it is working correctly, I wasn't using the recorder properly. Thank you very much for your help Vesna.

Re: rayleigh damping recorder

It seems that these two recorders are giving the velocity at the nodes instead of the Rayleigh forces (which is velocity times damping coefficient). has anybody compared the output of these recorders with velocity of the same nodes in the same DOF?

Re: Single-point constraint object & Time-History

Sorry, I haven't work with soil or pile modeling before. Maybe somebody who has more experience in this field can help. Just a general comment, make sure that the boundary conditions and assigned stiffness in the model with soil and pile are realistic.

Re: Running OpenSees files from Notepad++

You can use a batch file to run your model. When using the tclEditor, it also creates a batch file named exec.bat in the same location the model is. If you double click on it it will run your model. Make sure that the addresses in the batch file are referring to the correct locations and then you ca...

Re: Single-point constraint object & Time-History

If I understood your question well, in case you need the single point constraints to remain constant during your transient analysis, you have to use "loadConst" command after applying the single point constraint in order to make sure they don't change during the ground motion. http://opens...

static unloading / residual response

Hi, Is there a way to find the at rest position (residual displacements and forces) of the structure after a transient analysis? One way is to let the structure freely vibrates until the vibration amplitude becomes very small (like zero padding at the end of the ground motion vector). But free vibra...

Re: OpenSees 2.2.2 compile

Hi Frank, I am getting kind of the same linking error. I downloaded .zip source code and tried to compile it in VC++ 2010 and 2008 and got the same error in both versions. Here's the error: 24>element.lib(elementAPI.obj) : error LNK2019: unresolved external symbol __imp__Tcl_GetInt referenced in fun...
