Abstract :
Seismic Dampers have been used for years as
means to protect structures from adverse effects of
earthquakes. However, dampers cannot be placed in
buildings in a random fashion. The efficacy of dampers
depends on their location and orientation. The objective of
this experiment is to determine how any alteration in the
aforementioned factors affects the efficacy of these dampers.
In this project, 2D models were formulated and simulations
were run to determine the factors affecting the optimal
location and position of dampers. The simulations were run
on the ETABS software. The Response Spectrum Analysis
method was incorporated using the IS 1893-2016. The
results of this experimentation will help placing the dampers
in a building in an economic way. Dampers were found to be
most effective when placed in the lower storeys of a building.
Also, placing dampers closer to the centroidal axis increases
their efficacy. When placing dampers side to side, it is
recommended to place them in opposite orientations.
Orientation inversion is also recommended in consecutive
storeys. However, when it comes to giving priority to lower
storey or closeness to centroidal axis, the latter was found to
be the governing factor. Above results will help placing
dampers in the most efficient way, when the number of
dampers isrestricted.
