Use of hexagrid system for high rise buildings

Abstract

quotThe increasing scarcity of urban land has significantly limited the possibility of horizontal expansion in cities, thereby promoting the trend toward vertical development. One of the most practical solutions to address this constraint is the construction of tall buildings, which maximize land utilization through upward growth. However, as buildings increase in height, they become increasingly susceptible to lateral forces such as wind loads and seismic activities. These forces often become the dominant design considerations and necessitate the incorporation of specialized structural systems known as lateral load resisting systems (LLRS). newlineA variety of LLRS have been developed to enhance the structural stability and performance of high-rise buildings under such loads. These include systems such as shear walls, diagrid systems, hexagrid frameworks, exoskeleton structures, belt trusses, outrigger systems, tube-in-tube configurations, and composite systems that combine two or more of these techniques. newlineIn the present research, the Suvarna Bhumi Building an existing 14-storey high-rise located in Rajkot was selected as a case study to investigate the performance of hexagrid systems when employed as lateral load resisting mechanisms. Both horizontal and vertical hexagrid configurations were analysed under various load conditions. Key structural parameters were evaluated to determine the effectiveness and applicability of each system type across different building levels. newlineThe outcomes of this study contribute to a deeper understanding of the structural behaviour of hexagrid systems and offer insights into their feasibility and efficiency for future applications in tall building design.
