Shear Wall

[Imran]

Can any body give me any idea how to model shear wall on Opensees?
I have searhed in this forum but I could not found any one who has worked with shear wall.

One solution, you can use wide column and aggregate shear property. The other solution, you can try brick elements. But I recommend the first one.

Hope that helps,

What is the aspect ratio of your wall? If you are a flexure dominated wall, aspect ratio greater than 4, then using a NonlinearBeamColumn and just aggregating the shear resistance will get you pretty good answers if your wall is rectangular. Non-rectangular is another problem entirely.

Thanks for the answers, but how i i will define the support and can any give me the codes to model shear wall.

It is basically depends what kind of support you want chose. If you try a beam column element, then simply fix the bottom node.

Although I donot know whether I should I ask this question or not but if any body has time, pls answer. I want to put shear wall on bay two of the following picture. If I want to use nonlinearbeamcolumn element (It is a two node element), do i have to create new nodes on the middle of bay two and then create nonlinearbeamcolumn element and sized the element to fit between two columns?
