Dear How can I set the MPCurveParams in ReinforcingSteel model. As the default value for -MPCurveParams is 0.333 18 4. and these parameters are sensitive to the structural behavior. Does it have any limitations or literature support to set these parameters? Can i set -MPCurveParams 0.5 18 4. Thank y...

Thank you very much for your reply. Do you mean that 1. $rs has to equal $rc or $ro? Otherwise, straight-section hypothesis of strain would not be satisfied. 2. $nfCoreT can don't have to equal $numBarsSec? ///////////////////// (cover and the core have the same material IDconc1, $IDreinf placed at ...

Dear Dr.silvia: I have some questions about the fibre discretization of section. 1. Should the reinforcing bar fibre and the concrete fibre have the same place to satisfy the same stain?: section fiberSec $Col_Tag { patch circ $IDconc1 $nfCoreT $nfCoreR 0 0 0 $rc 0 360; Patch circ $IDconc2 $nfCoverT...

Dear Dr.silvia: What are the proper sizes (including radial divisions and theta divisions) for the circular section divisions. As I find that theta divisions equals to 8 in opensees examples, should i subdivide it if i want to get more precise results. Thank you very much. Best regards! david

Dear Dr.silvia:

When I tried Bond_SP01 in Opensees V2.1.0, I found that this command only supports ksi and inch units, not MPa and m.

Should I have to change the units before using Bond_SP01.

Best Regards!

It changes a lot beyond my expected
So i wonder whether there is other command that can control pdelta effects.

Dear Dr.silvia: I have a question about P-delta effects. If I want to consider P-delta effect while dealing with pushover analysis, should i just modify the command: geomTransf Linear 1 to geomTransf LinearWithPDelta 1 (in Opensees V2.1.0) When this modification is done, the result changes much comp...

Dear fmk: Once I have get the dll and lib file of new material, what should i do next to introduce it into opensees, so that new opensee.exe file can support new material command. Should i add dll file to certain folder and re-compile the opensees program? Thank you very much! Best regards!

Dear: I have downloaded the new version Opensees v.2.1.0. Can I compile the source code of Opensees v.2.1.0 in VC6.0. I found that there is no *.dsw file in it. After I convert opensees.sln into opensees.dsw using tool: proconverter.exe, there are still some fatal errors after i build the code. Such...

Dear Silvia, I have some problems about recorder command. 1. How can I record both the roof-displacement and total base shear force in the same output file using recorder command? (as i find that recorder command only support output of one type of response, e.g. node, element,etc. and whether it can...
