The rigidity of a shear wall is inversely proportional to its deflection under unit horizontal load.
In palestine the most lateral resisting forces construction forms is the cantilever shear walls system.
The total deflection of the shear wall can be determined from the sum of the shear and moment deflections.
The shear walls support the roof diaphragm laterally.
Note that the diaphragm has a weight and the walls have weights tributary to the diaphragm also.
Assume the roof of this building is a solid concrete slab rigid diaphragm of constant thickness.

Wall is based on its relative rigidity or stiffness.
Fully grouted shear wall required.
These walls may take many forms due to their functions and locations in the building.
On the next tab you can divide that total height into up to five different wall portions.
The building shown has shear walls indicated.

Flanged shear wall net area net moment of inertia shear area shear walls 10 m.
Reinforced concrete shear walls are the most frequently used forms of lateral resisting structural elements.
It is thus of prime importance to study the rigidity of these walls.
Equations for the deflection of fixed and cantilevered walls or piers are shown in fig.
Cantilever wall cant.
For illustration and comparison purposes the following figures provide a sample of the input modules and results obtained from an spwall model created for the reinforced concrete shear wall in this.
