SEISMIC ANALYSIS AND PERFORMANCE OF HIGH RISE BUILDING WITH DAMPER

Abstract

In day to day life, it is needed to study the behavior of every multi-storey building structure subjected to
ground motion which is the common problem for construction. The earthquake creates the vibrating forces at the base of
structure. These vibrations create the oscillations in building which may damage the structure tremendously. These
vibrations created at the ground level gets transferred up to the top of building and because of mass of structure which
produces the lateral forces on the frame which finally reduces the moment resistance capacity of building parameters
such as columns beams etc. For a decade, many strong Earthquakes also occurred one after another in many country.
These Earthquakes have cause severe damage to large-scale infrastructures. To protect structures from significant
damage and response reduction of structures under such severe earthquakes has become an important topic in structural
engineering. Structures are designed to resist and withstand dynamic forces by a combination of strength, deformability
and energy absorption. It indicates that structures designed with these methods are sometimes vulnerable to strong
earthquake motions. In order to avoid such critical damages, structural engineers are working on different types of
structural systems that can help to resist, provide strength and can withstand strong motions. Damper is one of the
effective system that withstand Earthquake. When Dampers used in high-rise buildings in seismic areas, it should reduce
the vibrations induced by lateral load i.e. strong winds and earthquakes. In the present study, a building with 25 floors is
analysed and also describe the study on seismic behavior of a structure with and without damper. The scope of present
study is to analyse behavior of multi-storeyed building for location of damper in structure system.
