Seismic Analysis of Floating Columns in RCC Structures with Different Soil Conditions

Abstract

Floating columns are aesthetically pleasing
and give more space for movement in the
parking lots of many multi-story buildings.
Floating columns are not inherently more
vulnerable to damage than ordinary
structures because of the way they are
designed. However, their application in a
building could provide certain design
challenges that need to be carefully taken into
account to ensure their overall stability and
structural integrity. This study examines the
drawbacks of floating columns at different
building sites. Models of the frame structure
are analyzed using STAAD PRO software of
the floating columns at different positions,
such as at the centre and the edge, for multistory
composite buildings using the structural
response of the building concerning response
spectrum method for different zones to
determine results like storey displacement,
periods, and mode shapes. The composite
construction with floating columns
surrounding its periphery performed better
than floating columns placed in the centre of
the building.
