When the primary function of structural walls is to resist in plane loads conveyed from diaphragms down to the foundation they are generally referred to as shear walls.
Special reinforced concrete shear walls.
Reinforced concrete shear wall analysis and design.
A structural reinforced concrete shear wall in a 5 story building provides lateral and gravity load resistance for the applied load as shown in the figure below.
A structural reinforced concrete shear wall in a 5 story building provides lateral and gravity load resistance for the applied load as shown in the figure below.
The design and detailing requirements for special reinforced concrete shear walls have undergone significant changes from aci 318 11 to aci 318 14.
In reinforced concrete buildings the vertical elements are usually either moment resisting frames or structural walls sometimes referred to as shear walls.
