Reinforced Concrete Shear Wall

Reinforced concrete shear walls have long been recognized as suitable structural systems providing both lateral resistance and drift control in rc buildings.

Reinforced concrete shear wall.

Introduction reinforced concrete walls are often used as elements for ensuring the lateral strength and stability of a structure. Shear wall section and assumed reinforcement is investigated after analysis to verify suitability for the applied loads. There are three types of action a reinforced concrete wall can be subjected to. Concrete shear wall buildings are usually regular in plan and in elevation.

During an earthquake a large amount of energy is released. In order for a structure. Construction codes of practice define maximum and minimum amounts of reinforcement as well as the detailing of steel bars. Horizontal and vertical distributed reinforcement ratio 0 25 is required for all shear walls.

Concrete shear walls are reinforced with both horizontal and vertical reinforcement figure 4. The action to which walls are most vulnerable is bending and this guidance note principally addresses this form of stress. Axial forces minor axis bending and shear and major axis bending and shear. However these older shear walls were typically designed for combined actions of gravity loads and wind loading.

Shear wall buildings are commonly used for residential purposes and can house from 100 to 500 persons per building.
