A Comparative Study of Flat Slab with Perimeter Beams and Conventional Slab Structures under Seismic Conditions

摘要

Flat slab structure are more convenient, economical and provide better architectural visibilityover conventional slab structure. But flat slab structures are flexible in nature and thus pose a threat to thesafety of the structure which brings us to find a method to overcome this disadvantage. Therefore,perimeterbeams are provided which imparts rigidity to the structure.Thispaperfocuses onthe comparative studyofconventional slab structureto flat slab structure having perimeter beams. In this study, ETABS software isused for the analysisof different structures in Indian seismic zones III, IV and Vhaving 10, 12 and 15 storeys.The models taken in this study have Rectangular and L shape configurations. On the basis of the analysisresults, the paper discusses the distinctions of structure’s behaviour under different heights in terms ofmaximumreaction, maximum storey displacement, maximum overturning moments and maximum storey drift.
