Abstract
The unexpected announcement of energy due to motion of the underground plates or rocks
over one another cause a break along a point, cause in Earthquake. Different areas have
different effect of earthquake thus Bureau of Indian Standards has group four Seismic Zones
in India, i.e., Zone II, III, IV, V. Therefore there is a need of a building to withstand the
displacement due to seismic load. This paper includes the study on the literature of
comparison of lateral displacement in a building with bracing and without bracing. It has
been concluded from literatures that installing the bracing in the structure can reduce the
lateral displacement of a building.
Keywords: Bracing, lateral displacement, seismic load
INTRODUCTION
Following the recent trends of earthquake
all over the world, it is observed that there
is very high risk for earthquake, thus
creating a need of earthquake resistant
structure. The tall structures are prone to
the seismic load and wind load. For this
purpose of enhancing the stiffness and
reducing lateral displacement there are
various methods to resist these lateral
loads like base isolation, formation of
hollow foundations, tuned mass dampers,
horizontal bands and bracings. Among
these application, bracing is one of the best
methods to resist these kinds of loads.
Bracing can be applied concentrically or
eccentrically. The cross bracings are one
of the mostly used types of bracing.
Bracings are very efficient in overcoming
the elastic seismic waves. This is used for
strengthening the building by increasing its
stiffness and displacement capacity
keeping the lateral displacement as low as
possible. Various types of bracings can be
used like X, V and Inverted V etc.
OBJECTIVE OF THIS STUDY
The objective of this is to find out the
comparison in the braced building and
unbraced building. This is to evaluate the
response of the braced frame and unbraced
frame under seismic loads, like base shear
and lateral displacement in a structure.
Beside the comparative study of both types
of frames, it was found that which types of
bracing is most suitable for earthquake
resistant structure.
LITERATURE REVIEW
Bharat Patel (2017), They examined the
base shear and lateral displacement for
G+10 structures like Moment Resisting
Frame (MRF), R.C.C building with V
bracing (VBF) and R.C.C building with X
bracing (XBF). The structures were
analyzed using ETABS for Seismic Zone
II. It was found that the base shear was
highest in XBF and lowest in MRF.
However the displacement was found for
every storey for each structure, and was
found that Displacement was highest in
MRF and this was reduced considerably in
XBF and VBF. These results concluded
