About This Video
In this video Er. Mayank Saini Corporate Trainer will Guide you About Steel Installation Process of Shear wall & Column .
Shear wall is a structural member in a reinforced concrete framed structure to resist lateral forces such as wind forces. Shear walls are generally used in high-rise buildings subject to lateral wind and seismic forces.
In reinforced concrete framed structures the effects of wind forces increase in significance as the structure increases in height. Codes of practice impose limits on horizontal movement or sway
Limits must be imposed on lateral deflection to prevent:
Limitations on the use of building,
Adverse effects on the behavior of non-load bearing elements,
Degradation in the appearance of the building,
Discomfort for the occupants.
Generally, the relative lateral deflection in any one storey should not exceed the storey height divided by 500.
The figure below shows the deflected profiles for a shear wall and a rigid frame.
One way to limit the sway of buildings and provide stability is to increase the section sizes of the members to create a rigid, moment-resisting frame.
However, this method increases storey heights, thus increasing the building cost. It is rarely used for more than 7 or 8 storeys.
Another way is to provide stiff, shear resisting walls linked to a flexible frame. These can be external walls or internal walls around lift shafts and stairwells (a core) or sometimes both are provided.
This shape and position of the walls give good flexural stiffness in the short direction, but relies on the stiffness of the frame in the other direction.
This arrangement provides good flexural stiffness in both directions, but may cause problems from restraint or shrinkage. As does this arrangement with a single core, but which does not have the problem from restraint of shrinkage.
