COMPARATIVE STUDY OF DIAGRID STRUCTURE WITH OTHER STRUCTURAL SYSTEMS FOR TALL STRUCTURES

The building became more and more slender because of vertical development due to less availability of land in recent year it is dangerous in the earthquake. In high rise buildings, lateral load governing force in design as the height of building increases, lateral load becomes more dominant than gravity load. Lateral load include Wind load and Seismic Load are act on the high rise building. These loads are resisted by various lateral load resisting systems. In this paper, discus aboutthe comparison of different types of lateral load resisting systems. The study mainly focuses on determining the most effective and economical system which can resist lateral load such as wind load and seismic load. Based on literature review, carry out comparative study of various lateral load resisting systems such as Shear wall, Belt Truss, Outrigger, Belt Truss + Outrigger, Diagrid, Staggered Truss, Tube in Tube system of 10 story structure with plan dimension of 18m X 18m. Analysis has been carried out using ETABS-2017 for different method of analysis for static earthquake forces, dynamic earthquake forces (Response Spectrum analysis as per guidelines of IS: 1893- (Part 1) 2016) and static wind forces as per IS 875 (Part-3)-2015 and design based on IS: 800-2000 and found that storey Displacements and storey drifts are observed to be less in Diagrid systems in X-Direction as compared to other lateral load resisting system
