Abstract
Modern architectural design and engineering often feature innovative structural systems, with diagrid structures standing out as an aesthetically appealing solution for tall buildings due to their geometrically complex patterns. Despite extensive global research on diagrids, a comprehensive study systematically comparing their structural efficiency is still lacking. The structural efficiency and seismic performance of diagrid lateral load-resisting systems were evaluated in this thesis. The study compared the diagrid system’s effectiveness against conventional building designs across low-rise, mid-rise, and high-rise buildings under seismic loads. Using ETABS v17.0 software, response spectrum analysis was conducted to assess storey displacement, storey drift, base shear, and time period in both X and Y directions for 12 models.The study reveals that diagrid systems outperform conventional structures by significantly reducing storey displacement and drift, increasing base shear capacity, and shortening the time period across varying building heights. Overall, these findings underscore the diagrid system’s superiority in seismic conditions, urging its wider adoption in earthquake-prone regions for improved building safety and performance.
Keywords: Diagrid structures, seismic performance, structural efficiency, storey displacement, storey drift, base shear, time period, ETABS, low-rise buildings, mid-rise buildings, high-rise buildings, etc.
