Seismic and Wind Analysis of Different Lateral Load Resisting Systems

The rapid increase in the population andscarcity
of land has increased the demand of taller buildings.
Expanding the building vertically seems to be anefficient
option considering all the factors. The resistance of tall
buildings to wind as well as to earthquakes is the main
determinant in the formulation of new structuralsystems
that evolve by the continuous efforts of structural engineers
to increase building height while keeping the deflection
within acceptable limits and minimizing the amount of
materials. As the building height increases role of lateral
load (Wind and Seismic) resisting systems becomes more
prominent as compared to gravity load resisting system.
Basically, there are three main types of buildings: steel
buildings, reinforced concrete buildings, and composite
buildings. The following research paper emphasizes on
different types of lateral load resisting systems and how
they react to different loads acting on them. The buildings
modelled are done using Etabs software. The buildings are
analyzed for both static as wellas dynamic analysis. Static
analysis is carried out using ESM (Equivalent Static
Method) and dynamic analysis is carried out using RSM
(Response Spectra Method). The modeling is done to
examine the effect of different cases onseismic and wind
parameters like base shear, lateral displacements, lateral
drifts and stiffness for zone-IV in medium soil as specified
