Shear wall model

Postby samsonama » Wed Mar 02, 2016 1:04 am

Hei,
I am a new user in Opensees. The structure consist of a shear wall and column. The analysis that will be computed are:
-Modal Analysis
- Pushover Analysis
- Non-Linear Time-History Analysis

The questions that raise up are:

- It is better to model it in 2D or 3D
- If 2D, which element type and section should I use
- If 3D, which element type and section should I use

The shear wall varies in thickness and reinforcement along the height, and withstands the shear forces.


Thank you.

if you have no 3d effects model as 2d.
if 2d you can moel the column with beam column elements with fiber discretization. the wall could also be modeled using this approach, but regualrize the material properties.

the wall can also be modeled as a continuum element, as i don't think there is a way at present to build a layered plane-stress material for the quad element.

The objective of this study is to model the non-planar shear walls of asymmetric shear wall-frame building structures in elastic range.The elaboration of this simplified model is realised in several stages. The first stage is devoted to the inelastic finite element analysis of a shear wall which was tested under pseudo dynamic loading.Custom essay writing service (http://www.essayguardian.com/) offers its reliable writing help with all types of written assignments.

I think it is 3D. In this, we can easily identify all things. It will be more suitable for you. Thanks for this.
