We are collecting OPENSEES User-Requirements Data

If you have a script you think might be useful to others post it
here. Hopefully we will be able to get the most useful of these incorporated in the manuals.

Hi! , Silvia
I am beginner in opensees and need your help with regard to modeling steel damper as bilinear or tri linear force-deformation relation.
My aim to model steel damper in order to make the comparison of hysteretic curve which obtained from experimental test with simplified model. In bilinear model the input data is elastic stiffness, yield force or yield displacement and post yield stiffness ratio , while the loads is cyclic increasing displacement. for example 0 1 0 -1 0 2 0 -2 0 4 0 -4 ....so on. After that I want to calculate the area under hysteretic curve as hysteretic energy. What type element should be used if the material data is not stress-strain but force-displacement. your help is highly appreciated.

Regards
Daniel

Hi
thank youuuuuuuuuu
As a user I need some example for modeling of steel plate shear wall in 2D and 3D frames

Hi all
Can I get some examples for bridge modeling?
It will be very very helpful
Thanks :)

Hi
I have modeled a TMD in a 5 story 3D RC structure and I have carried out a Time history analysis of it. But the displacements are the same when there is no TMD. I will write down it's part of my scripts. Please helllllp me. thanks

Hello Sir,
I want the examples of --
1. Free field liquefaction analysis
2. Soil structure interaction and
3. Soil foundation modelling
I am doing my project on Seismic requalification of geotechnical structures in OpenSees for which I will require the above examples and also site response analysis which is already there in OpenSees geotechnical examples. I have to model a soil foundation system of a bridge in liquefiable soil. Therefore I request you to kindly post these examples as early as possible.

Thanking You

Dear sir,

as opensees user I need the following examples
1.some modeling of bridge with pile foundations and abutment soil- structure interaction
2. lead rubber bearing and elastomeric bearing models for highway bridges
3. kelvin and voit model of bridge pounding

Thanks to this post, which is designed to meet the needs of users. I must say that examples of the bridge are very rare.
