Coupling beams dissipate the energy along with preventing the major damage in the shear wall. Shear wall location might vary from an architectural and functional point of view. However, it may be possible to find the ideal location of the shear wall by analysis of various parameters such as story displacement, base shear, story drift, etc.
Shear wall is best to locate in the middle of the structure or building causing symmetricity. The shear wall at such location helps to decrease the shear force symmetrically and equally in all parts. Thus it is best to locate the shear wall along with lifts or the stairs as the lifts or stairs are located in the middle of the structure as much as possible for better accessibility. Moreover, there will not be any opening needed for the wall at stairs or elevators, so shear wall with no openings can be constructed for better performance.
But it is not always possible or economical to construct the shear wall a middle, so the wall can be also formed at the corners or external faces of the buildings. However, their efficiency is not much as maximum as placed at the asymmetrical points. Shear walls can be located along the shorter dimensional plane of the structure where the relative distance between the column is relatively greater and it is uneconomical to provide column between them.
The larger dimension of the structure consists of numbers of the column placed relatively nearby each other compare to shorter so, they might not need it. Whatever the location can be, it must be kept in order to maintain symmetry to prevent ill effects and twist in structure.
The shear wall must be located in such a way that, there is a maximum probability of lateral load is predicted to apply along the plane of the shear wall. So the seismic behavior of the place is first well studied and the movement of lateral forces that are most probable to be caused in a certain direction are fixed out according to which the location and direction of the plane of the shear wall are suitably located.
The simple provision for design of shear wall is illustrated in IS The some of major specification or thumb rules are,.

However, the column is very weak in case of lateral load, buckling load or shear load. Shear wall, on the other hand, is designed to resist lateral load by shear strength or shear action.
