COMPARATIVE ANALYSIS OF A HIGH RISE BUILDING FRAME WITH AND WITHOUT DIAGRID EFFECTS UNDER SEISMIC ZONES III & V

The diagrid system nowadays widely used for high rise buildings due to its structural efficiency. In present research work, steel diagrid structure at an outer portion of the building at 60 degrees having an inner core of R.C.C columns with R.C.C beam and the slab is analyzed and compared with a conventional concrete building. The diagonal member of diagrid structure transferred the lateral loads by axial action compared to bending of vertical columns in the conventional building system. A regular eleven storey RCC building with plan size 16 m × 16 m located in seismic zone V & III is considered for analysis. STAAD.Pro software is used for modeling and analysis of structural. Seismic zone is considered as per IS 1893(Part 1): 2002. The Comparison between the diagrid and conventional building analysis results presented in terms of a node to node displacement, bending moment,storey drift, shear forces, an area of reinforcement, and additionally the economical aspect.
