| dc.description.abstract | This study undertaken to carry out comparative analysis of buildings with different slab
systems by using ETABS 18.1.0 and to compare the analytical results with different
slab system and also to conduct a parametric study on the lateral strength of building
with different load combination. Total six models, three of G+6 and three of G+11
building was analyzed to compare the results of different parameter. This paper focuses
on the comparative study of Beam Supported slab structure to flat slabstructure. In this
study, ETABS 18.1.0 software is used forthe analysis of different slab supported
structures with BNBC 2020 in seismic zone IV.The models taken in this study have
rectangular configurations for residential building. Flat slab structure is more
convenient, economical and provide better architectural visibility over Beam Supported
slab structure. But flat slab structures are flexible in nature and thus pose a threat to the
safety of the structure which brings us to find a method to overcome this disadvantage.
The paper discusses the distinctions of structure’s behavior under different slab in
terms of maximum story displacement, maximumstory drift and story stiffness. The
story displacement of flat slab is approximately three times than Beam Supported slab.
The story drift is also same as story displacement. The stiffness of Beam Supported slab
structure is approximately four times than flat slab and two times for G+6 story. The
stiffnessof Beam Supported slab supported structure is approximately three times than
flat slab and two times than flat slab with perimeter beam for G+11 story. This is
due to Beam Supported slab structure has a greater stiffness than flat slab structure.
