Shear wall can also be defined as a wall which are reinforced made of braced panels to carry lateral forces.

The thickness of the shear wall for regular buildings can be generally in the range of 150 mm to 400 mm.

Shear Wall in a Building Functions of Shear Wall: The main functions of a Shear Wall can be described as follows: Providing Lateral Strength to building: Shear Wall must provided lateral shear strength to the building to resist the horizontal earthquake forces, wind forces and transfer these forces to the foundation.

Providing Lateral Stiffness to building: Shear Walls provide large stiffness to building in the direction of their orientation, which reduces lateral sway of the building and thus reduces damage to structure.

Load Transfer Mechanism: Shear walls carry Horizontal Seismic forces downwards to the foundations.

Thus, design of their foundations requires special foundations.

The various walls and co-existing frames in a building are linked at the different floor levels by means of the floor system, which distributes the lateral loads to these different systems appropriately.

The interaction between the shear walls and the frames is structurally advantageous in that the walls restrain the frame deformations in the lower storey, while frame restrain the wall deformations in the upper storey.

Load Transfer mechanism in Shear Walls The load attracted to each component is a function of position and relative stiffness.

Compared to cantilever shear walls, stiff frames and short shear walls when subjected to horizontal load deform with a pure shear behavior, with a concave shape in the upper region and convex in lower region.

Whereas cantilever shear walls has a flexural behavior, the deflection is convex like a BMD of a cantilever beam, throughout the height of the wall.

So, ht 3000 100 30 mm lt 4000100 40 mm Assume, both ends fixed ( restrained against rotation displacement ) L (eff.) 0.75lo, where, lo is least of length height 0.75 3 2.25 m L (eff.) t 2250100 22.5 12 As per Indian Standard, Permissible value of L (eff.)t 45 22.5 e (min.) t20 or 20 mm 5 or 20 mm Therefore, moment due to accidental eccentricity of 20 mm is considered.

Since Vertical Reinforcement is less than 2, no horizontal links are required.
