No. I meant using the pinching parameters in the hysteretic material

you should use the pinching parameters in x and y axes. The link below shows pinching parameters of 0.2 and 0.6.

Hi all in dynamic analysis, I am getting Jagging behavior in hinge moment-rotation curve when the stiffness changes to negative as shown in the pic in the link below I am using ModIMKPeakOriented material for the plastic hinges. I got the same jagging using the Hestritic material. under cyclic stati...

I am not an expert, but I had the same issue. The axial force in fiber elements is caused by restraining the elements from expansion. Concrete fiber elements expand when subjected to moment. that is because the axial displacement of the element is calculated by integrating the strains at midsection ...

Did you solve this problem?

Thank you all.

Hi all
Is it possible in Opensees to apply DisplacementControl on two points (or more) at the same time?

Thanks for your reply.

Hi I am using Ibarra- Medina-Krawinkler Hysteretic model for concrete columns. The parameters for concrete columns can be obtained from (PEER 2007/03) by Haselton et al. The parameters for steel members can be obtained from Blume report (TR 177) By Lingnos and Karawinkler. Both reports are accessibl...

Hi I noticed when a lateral load is applied to a reinforced concrete fiber element (column element), the element undergoes upwards displacement. This happens with or without axial load. Furthermore, when the same element is assigned linear elastic (or steel) properties there will be no upwards displ...

Thanks for your reply.

Hi all

The link provided to browse the source code is not working.

http://opensees.berkeley.edu/WebSVN/lis ... runk%2FSRC

is it not working or a permit is required?
I accessed the link months ago and it was working.
