Structural Performance of Diagrid Systems in High-Rise Buildings with Different Geometrical Configurations

Abstract

The diagrid structural system has been widely used for recent tall buildings due to the structural efficiency and aesthetic potential provided by the unique geometric configuration of the system. Diagrid is a system of triangulated beams, straight or curved, and horizontal rings that together make up a structural system for skyscrapers. Diagrid structures carry lateral seismic loads much more efficiently by their diagonal member’s axial action in comparing with conventional orthogonal structures for tall buildings such as framed tubes. The configuration and efficiency of a diagrid system reduce the number of the structural element required on the facade of the buildings. Current study is to investigate G+15 multi-storeyed R.C.C building using Etabs 2016 software. Seismic analysis is done by response spectrum. Building models with different geometrical Shapesd Square &T shaped are analyzed by Etabs software to study of the effect storey shear, base shear, storey stiffness, maximum storey displacement and maximum storey drift etc.
