Recinforced Concrete Shear Wall

There are three types of action a reinforced concrete wall can be subjected to.

Recinforced concrete shear wall.

Shear wall section and assumed reinforcement is investigated after analysis to verify suitability for the applied loads. For walls designed in. Plain concrete wall when reinforcement 0 4 reinforced concrete wall when reinforcement 0 4. Shear walls are generally used in high rise buildings subject to lateral wind and seismic forces.

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. The design and detailing requirements for special reinforced concrete shear walls have undergone significant changes from aci 318 11 to aci 318 14. The coe cient of normal force influence can have a value of 0 cw 1 25. 2012 paterson 2003 on full scale thin shear.

Shear walls are typically light framed or braced wooden walls with shear panels reinforced concrete walls reinforced masonry walls or steel plates. The action to which walls are most vulnerable is bending and this guidance note principally addresses this form of stress. Saatcioglu 2013 demonstrates that these thin reinforced concrete shear walls were severely damaged laboratory studies hamed et al. Experience from recent earthquakes wallace 2012.

To learn more about these deficiencies refer to the applied technology council atc 40 seismic evaluation and retrofit of concrete buildings report. Reinforced concrete wall is designed as a compression member. 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. Reinforced concrete wall is used in case where beam is not provided and load from the slab is heavy or when the masonry wall thickness is restricted.

Plywood is the conventional material used in wood timber shear walls but with advances in technology and modern building methods other prefabricated options have made it possible to inject. Axial forces minor axis bending and shear and major axis bending and shear. Shear wall analysis and design spwall software. Shear wall is a structural member in a reinforced concrete framed structure to resist lateral forces such as wind forces.

Reinforced concrete wall is classified as. Spwall is a program for the analysis and design of reinforced concrete shear walls tilt up walls precast wall and insulate concrete form icf walls.
