In this post, we are going to review how shear walls can be modelled on Staad Pro software and consider the various accuracy levels with each method.

Let us consider the shear wall shown below;

Thickness of the wall = 250 mm

The wall is subjected to a lateral load of 300 kN at the top.

**Model 1**: Equivalent frame model

In this model, we represent the shear wall as an equivalent frame with representative stiffness for the various elements.

On modelling this Staad Pro, we obtained the result shown below;

The maximum horizontal deflection was obtained to be 158.376 mm.

**Model 2**: Plate modelling (Finite Element Mesh)

In this model, the shear wall is modelled as a full plate with approximate mesh size of (4 x 4) per square metre. The deflection due to the lateral load is given below;

The maximum horizontal deflection was obtained to be 156.588 mm.

It is important also to compare the deflection obtained by considering different mesh sizes in order to compare the accuracy of utilizing the equivalent frame model. Thank you for visiting Structville today, and God bless.
