The shear walls support the roof diaphragm laterally.
On the next tab you can divide that total height into up to five different wall portions.
Assumed properties shall not exceed half of gross section properties unless a cracked section analysis is performed.
Elwood k j et al.
Determine stiffness from basic principles.
Assume the roof of this building is a solid concrete slab rigid diaphragm of constant thickness.
Note that the diaphragm has a weight and the walls have weights tributary to the diaphragm also.
It is thus of prime importance to study the rigidity of these walls.
In palestine the most lateral resisting forces construction forms is the cantilever shear walls system.
The building shown has shear walls indicated.

Cantilever wall cant.
The total deflection of the shear wall can be determined from the sum of the shear and moment deflections.
Fully grouted shear wall required.
Shear wall concrete strength in plane and out of plane is calculated for the applied loads and compared with the code permissible shear capacity.
This module allows the design of concrete shear walls including multi story walls with no openings but with up to five levels of differing length height and thickness.
The rigidity of a shear wall is inversely proportional to its deflection under unit horizontal load.
