Multi-storey building construction is increasing day by day throughout the world. The design and construction of artificial infrastructure on the lines of bio-mimicking principles require the development of highly advanced structural system which has the quality of aesthetic expression, structural efficiency and most importantly geometric versatility. Recently, the use of diagonal members for carrying the gravity and lateral load has increased and these members are known as ‘diagrid’. The unique geometrical configuration of the diagrid structural system has led them to be used for tall buildings providing structural efficiency and aesthetic potential. The study done in this paper by considering aspect ratio 1:1, 1:2, 1:3 and 1:4. Diagrid angles 33.69°, 53.13°, 63.43°, and 69.44° for G+60 story building. The behaviour of structure under the action of wind load is studied. Also optimum angle for the prepared diagrid models will be studied. Software that will be used is ETABS 2015.
