Reinforced Concrete Shear Wall

However these older shear walls were typically designed for combined actions of gravity loads and wind loading.

Reinforced concrete shear wall.

There are three types of action a reinforced concrete wall can be subjected to. Concrete shear walls are reinforced with both horizontal and vertical reinforcement figure 4. Concrete shear wall buildings are usually regular in plan and in elevation. Reinforced concrete shear walls have long been recognized as suitable structural systems providing both lateral resistance and drift control in rc buildings.

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

Axial forces minor axis bending and shear and major axis bending and shear. Shear wall section and assumed reinforcement is investigated after analysis to verify suitability for the applied loads. 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 reinforcement ratio is defined as the ratio of the gross concrete area for a section taken orthogonal to the reinforcement.
