ABSTRACT
This paper discusses importance of the lateral stiffness of a building on its wind and seismic design. To reduce
damage in the event of wind and an earthquake, it is desirable to have large lateral stiffness. Shear walls
contribute significant lateral stiffness, strength, and overall ductility and energy dissipation capacity. Therefore
we have introduced shear walls at different location on plan of building like side centre shear wall, corner
shear wall, shear wall at near to centre of building plan. The effect of shear wall on deflection is studied in A1,
B1, C1& D1 models of 30 storied building.

KEYWORDS: Deflection, position of shear wall.

INTRODUCTION

Tallness, however, is a relative matter, and tall building cannot be defined in specific terms related
just to height or to the number of floors. From the structural engineer’s point of view, however, a tall
building may be define as one that, because of its height, is affected by lateral forces due to wind or
earthquake actions to an extent that they play an important role in the structural design .The influence
of these action must therefore be considered from the very beginning of design process. Tall towers
and building have fascinated mankind from the beginning of civilization, their construction being
initially for defence and subsequently for ecclesiastical purposes. The growth in modern tall building
construction, however, which began in the 1880s, has been largely for commercial residential
purpose. Tall commercial buildings are primarily a response to the demand by business activities to be
as close to each other, and to the city centre, as possible, thereby putting intense pressure on the
available land space.
Loading on tall building differs from loading on low-rise building in its accumulation into much
larger structural forces, in the increased significance of wind loading, and in the greater importance of
dynamic effects. The collection of gravity loading over a large number of stories in a tall building can
produce column loads of an order higher than those in low-rise building surface, but also with greater
intensity at the greater heights and with a larger moment arm about the base than on a low-rise
building. Although wind loading on a low-rise building usually has an insignificant influence on the
design of the structure, wind on high-rise building can have a dominant influence on its structural
arrangement and design in the wind may have to be considered in assessing the loading applied by the
wind. In earthquake regions, any inertial loads from the shaking of the ground may well exceed the
loading due to wind and, therefore, be dominant in influencing the building’s structural form, design,
and cost. As an inertial problem, the building’s dynamic response plays a large part in influencing,
and in estimating, the effective loading on structure.
