Re: OpenSees version

The new versions of OpenSees does not require a separate installation of tcl.

Re: Analysis of bending moment and curvature of section

Do you have the "curve-moment.tcl" file in the same folder?

Re: Time history analysis got same result with different model

It could be possible that the units of the ground motion file could be different (like g's), whereas the model unitc could be in inch. So, the larger motion that you think you are applying could still be a small motion.

You can also check the references here: https://opensees.berkeley.edu/wiki/inde ... 4_Material

The quoFEM application of the SimCenter also allows calibration of OpenSees material models. https://simcenter.designsafe-ci.org/res ... plication/

Re: Time history analysis got same result with different model

The ground motions that you are using in time history analysis could be small that does not result in inelastic response.

Re: Pushover analysis error help

This means that you are experiencing convergence problems and analysis fails because it cannot satisfy the convergence test. From the messages, it looks like it happens post-peak at the descending portion of the pushover. Could you plot the pushover curve and see if the analysis continued until a re...

Re: Question on using rigid diaphragm for a RC frame with fiber sections

There can be two solutions to overcome this issue:

1) Define the beam cross sections using force-resultants (i.e. moment-curvature) instead of fiber sections
2) Use zerolength element at the ends of the beams with very small axial stiffness along the beam longitudinal direction

Re: Stress-Strain Fiber Outputs

Hello, In a displacement-based beam-column element, curvature is linear along the length of the element, therefore use of a single displacement element is not sufficient to properly model the inelastic response in your column. You should either use multiple displacement based elements, or use a forc...

Re: Changing Node ID in OpenSees Example

It is likely because the node numbers used in the base shear recorder need to be updated as well.
