The OpenSees Community

Thank Selimgunay for your reply. Could I kindly get your email ID? I am a little new to opensees. I have to calibrate parameters to fit the response of a "connection", which was experimentally tested. The monotonic and cyclic response of the connection is available (experimental force and ...

Hi Forum, My hysteresis loops have strength degradation, stiffness degradation, and pinching. I need to consider all three aspects, in my dynamic analyses. However, In Opensees, Bouc Wen model does not consider pinching while BWBN considers pinching, but does not consider degradation. Any suggestion...

Dear FMK, Is a preliminary version available available in binary form yet. I have been trying BW and BWBN too. The complete version, will be very useful for the community.

For BWBN parameter estimation,
I am facing a MATLAB error with the BWBN simulink code provided on the Opensees Example page. M file and the .MDL file are here -

Could someone please help.

Thank you very much, IsmBaha. I will fix the code, accordingly.

1. The 20 earthquake records seem correct. 2. The IDA procedure (SACdynamicals.tcl and SACeqscale.tcl) seem correct. 3. The file Model.tcl seems correct. 4. The MATLAB file run_ops.m seems correct. 5. Could someone check these 2 files: drift_rw_1.m and SACgravity.tcl. There may be problem. (6 direct...

Hi Forum,

There is a BWBN hysteresis example on opensees website. http://opensees.berkeley.edu/wiki/index.php/BWBNExample

However there is an error, when one runs the MATLAB code, as the output files are not generated. Could the moderator /FMK kindly look at it.
