STUDY ON DIAGRID STRUCTURE OF MULTISTOREY BUILDING

Abstract

Construction of multi‐storey building is rapidly increasing throughout the world. . Recently the diagrid
structural system has been widely used for tall buildings due to the structural efficiency and aesthetic potential provided
by the unique geometric configuration of the system.These days the latest trend of technology in diagrid structures is
evolving. The diagrid structures are buildings with diagonal grids in the periphery at a particular angle and in modules
across the height of the building. Diagrid structure uses triangulated grids which are in place of vertical columns in the
periphery. Thus, systems that are more efficient in achieving stiffness against lateral loads are considered better options
in designing tall buildings.
This paper presents a stiffness-based design methodology for determining preliminary member sizes of r.c.c diagrid
structures for tall buildings. A G+24, G+36,G+48,G+60 storey RCC building with plan size 18 m × 18 m located in
surat wind and seismic is considered for analysis. STAAD.Pro software is used for modelling and analysis of structural
members. All structural members are designed as per IS 456:2000 and load combinations of seismic forces are
considered as per IS 1893(Part 1): 2002. Comparison of analysis results in terms of beam displacement, Storey Drift,
Bending Moment. This cause economical design of diagrid structure compared to conventional structure.
