Reinforced Concrete Shear Walls

Shear wall is a structural member in a reinforced concrete framed structure to resist lateral forces such as wind forces.

Reinforced concrete shear walls.

The design and detailing requirements for special reinforced concrete shear walls have undergone significant changes from aci 318 11 to aci 318 14. Reinforced concrete shear wall analysis and design. Reinforced concrete walls are often used as elements for ensuring the lateral strength and stability of a structure. Reinforced concrete shear wall analysis and design.

The action to which walls are most vulnerable is bending and this guidance note principally addresses this form of stress. 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. Reinforced concrete wall is classified as. 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.

Their benefits such as high load carrying capacity and high energy dissipation make them an attractive alternative in the construction of high rise buildings particularly in areas of seismic activity. The changes are a result of the unsatisfactory performance of many shear walls in the chile earthquake of 2010 and the christchurch new zealand earthquake of 2011. Wall thickness varies from 40 mm. During an earthquake a large amount of energy is released.

Axial forces minor axis bending and shear and major axis bending and shear. There are three types of action a reinforced concrete wall can be subjected to. Reinforced concrete shear walls have long been recognized as suitable structural systems providing both lateral resistance and drift control in rc buildings. The lateral and gravity load resisting system consists of reinforced concrete walls and reinforced concrete slabs.

Reinforced concrete wall is designed as a compression member. Reinforced concrete rc shear walls are commonly used in high rise buildings to resist lateral loads such as winds and earthquakes. Shear wall section and assumed reinforcement is investigated after analysis to verify suitability for the applied loads. However these older shear walls were typically designed for combined actions of gravity loads and wind loading.

Shear wall section and assumed reinforcement is investigated after analysis to verify suitability for the applied loads. Shear walls are the main vertical structural elements with a dual role of resisting both the gravity and lateral loads.
