Abstract :
Progressive collapse causes the failure of
primary structural member to propagate to the
adjoining member, thus causing the collapse of the entire
structure. The need to mitigate the impact of progressive
collapse is necessary as it leads to catastrophic economic
loss and causalities. The flat slab buildings are more
prone to progressive collapse due to the absence of
beams which are used to transfer the load initially
resisted by the removed column. The main cause of
failure in a flat slab building is the punching shear
failure occurring at the slab column connections. The
main objective of the analysis is to study the different
force acting on building. To Study the progressive
behavior of flat slab of G + 10 storey L and C shaped
asymmetrical plan building for removal of column from
different location (interior, exterior and corner). The
progressive collapse analysis was carried out with the
help of commercially available software named ETABs
16. The critical members were removed. The analysis
was carried out by referring General Services
Administration (GSA-2013, Revised 2016) and Unified
Facility Criteria - Department of Defense (UFC - DoD-
2009, Revised 2016) guidelines. For flat slab without
drop panel structure when longer side middle column is
removed the maximum vertical deflection in L plan
building is around 1/2 of maximum vertical deflection of
C plan. Flat slab without drop panel structure when
outer corner, inner corner and middle column removed
maximum base shear in L plan building is around 1/2 of
maximum base shear of C plan. From the analysis results
it was found out that L plan and C plan buildings, L plan
building performed better.
