Reinforced Concrete Shear Wall

Reinforced concrete shear wall analysis and design.

Reinforced concrete shear wall.

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. Concrete shear walls are reinforced with both horizontal and vertical reinforcement figure 4. Axial forces minor axis bending and shear and major axis bending and shear. In order for a structure.

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. During an earthquake a large amount of energy is released. Horizontal and vertical distributed reinforcement ratio 0 25 is required for all shear walls.

Reinforced concrete shear walls have long been recognized as suitable structural systems providing both lateral resistance and drift control in rc buildings. There are three types of action a reinforced concrete wall can be subjected to. The action to which walls are most vulnerable is bending and this guidance note principally addresses this form of stress. Construction codes of practice define maximum and minimum amounts of reinforcement as well as the detailing of steel bars.

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