Today Post-tensioning is a mature technology, providing efficient, economic and elegant structural solutions
for a wide range of applications. Post-tensioned flat slab could be a better option compared to RCC flat slab, in respect
of the cost of project and time of construction.The aim of this project is to compare the behaviour of RCC flat slabs, Posttensioned flat slabs and conventional structure and also to analyze the behaviour of Post-tensioned flat slab structure
with and without shear walls under seismic effect.In multi-storey framed structures flat slabs have weak resistance to the
lateral loads. So to provide stiffness to structures against lateral forces shear walls are used. In this paper, a study of 15
storey building in zone IV is considered, and a comparative analysis of conventional structure with Post-tensioned and
RCC flat slab is done to determine various parameters like base shear, storey drift, and displacement. Also, the building
is analyzed with Post-tensioned flat slab by changing various location of shear wall. ETABS 2016 software is used for
the analysis.
