Abstract- During an earthquake, failure of structure starts off-evolved at factors of weak spot. This weak point arises due to discontinuity in mass, stiffness and geometry of structure. The systems having this discontinuity are termed as irregular systems. Irregular structures contribute a massive portion of city infrastructure. The effect of vertically irregularities within the seismic overall performance of systems will become definitely vital. Whilst such buildings are built in high seismic zones, the analysis and design turn into more complexes. The main objective of the analysis is to study the behaviour of flat slab system in vertical irregular multi-storied building against different forces acting on it during earthquake. Also, the objective of analysis is to study the structural behaviour of shear wall – flat slab interaction with opening. The analysis is carried out using STAAD Pro2007 software. Flat slab system with shear wall are modelled and analysed for the dynamic loading. The analysis is made between in the three types of G+9 storey building with 0 % vertical irregularity, 200 % vertical irregularity and 300% vertical irregularity. In all these building’s shear wall is provided with & without 20% opening. Total 15 modelled are studied and their results were compared. Response spectrum analysis results provides a more realistic behaviour of structure response hence the analysis of flat slab system in regular, 200% Irregular and 300% Irregular multi-storied buildings without shear wall and buildings with shear wall at different location & opening is carried out. It’s concluded that the flat slab Structure with shear wall along central periphery is suitable for the effect of dynamic load on the performance of building & negligible effects of opening of size 20% of the shear wall on the stiffness of the system. Comparison in made between Stresses & Bending Moment on flat slab, node displacement, Base shear, Story drift & the result are brought out.
