Abstract
Due to increasing in population as well as
less availability of land it is necessary to construct
multi-storey building. Underground storeys
(basements) are an important component of urban
building construction for reducing parking problem.
To study the behaviour of this type of building under
seismic loading is main objective of this analysis.
When we are considering underground storeys it is
necessary to consider Soil-Structure Interaction effect.
The dynamic interrelationship between the response of
the structure is influenced by the motion of the soil
and the soil response is influenced by the motion of
structure is called a soil structure interaction. Here,
we are considering Soil-structure Interaction effect on
building with vertical irregularities. G+14 storey
building is selected for modelling and analysis.
Response spectrum and Time History Analysis is done
in SAP2000. Response spectrum analysis and Time
history analysis is carried out according to IS
1893:2002 and acceleration data of past earthquake
respectively. The effect of SSI on various structural
compound like time period ,base shear, roof
displacement ,are studied and discussed.
