Abstract

The rapid growth in population in urban area has given rise to the increase in construction
of multi storey buildings in urban area to reduce the pressure of accommodation. In recent
time designing aesthetically beautiful and complex buildings which has irregularities in plan,
vertical irregularity, mass irregularity etc are done. But for high rise multi storey building the
wind loads and seismic loads play dominant role. Buildings with irregularities suffer more
damage than regular buildings when subjected to wind and seismic loads. Bracings, shear
wall are some of the structural elements which can resist lateral loads. Bracings are highly
effective and economical method of resisting seismic and wind loads. The objective of this
study is to study the behaviour of building with bracings and without bracings under different
seismic and wind zones using ETABS 2016 software. In this project the bracings selected are
X bracings, v bracings, inverted v bracings. The bracings which gives better lateral resistance
is found after analysis. In this project seismic analysis is done in two methods Response
Spectrum analysis and Time History analysis and the deviation in results between the two
methods are investigated.
