In recent years the population is increasing rapidly. Due to this reason the demand for housing is high as every year passes which results in saturation in area consumption. High rise buildings provide an effective and economical explanation for the problem. Tubular system is recent form of high rise building in order to resist lateral load. These are mainly of three types, diagrid, hexagrid and octagrid. Hexagrid system is form of new system for high rise building which were designed on strength and stiffness to withstand wind load and seismic load on a storey height more than 50. The study is mainly going to discuss about the behavior of high rise building using hexagrid system with different hexagrid sizes in module under earthquake loading. The optimum module sizes will be obtained for both equivalent static and non-linear dynamic analysis. A G+59 storey building with symmetric floor plan using equal consumption of steel for the different hexagrid sizes will be modeled in ETABS 2016. The examination and the investigation of conduct of the hexagrid with various module sizes will be examined. © BEIESP.
