Abstract

Now a day’s construction of high rise building is rapidly increasing throughout the world. Therefore the diagrid structural system is most widely used for high rise buildings because of its structural efficiency and aesthetic look. The diagride structure is a type of structure in which the diagonal members are used in the periphery of the structure. In present work concrete diagride structural system with corner column and without corner column is analyzed and compared with conventional structural system. Due to inclined columns in the periphery, lateral loads are resisted by axial action of the diagonal in diagrid structure compared to bending of vertical columns in conventional structure. A regular G+18 storey RCC building with plan size 20mX20m located in seismic zone III is
considered for analysis. STAAD.Pro software is used for modelling and analysis of structural members. All the structural members are designed as per IS 456:2000 and load combinations of seismic forces are taken as per IS 1893(part 1):2000. Comparison of results on terms of axial force, bending moment, shear force and displacement is presented. Thus it can be concluded that behaviour of diagrid structural system with corner column is more efficient than diagride without corner column and conventional structural system
