Abstract:

Multi-story 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. In this study, the structural response and comparative analysis of nodes with hinged or fixed connections for rectangular and curved planner shape diagrid building is investigated to evaluate the structural benefits of diagrid system. A regular G+15 story steel building with a plan size of 18 m x 18 m rectangular and 30m x 13m curved planner shape, located in a seismic zone V is analyzed by STAAD Pro. Software. All structural members are analyzed as per Indian standard loading standard (IS 875 (Part1) for dead and (IS 875 (Part2) live loads. Also the seismic forces are considered as per earthquake resistant design of structure (IS 1893 (Part 1): 2002).
