Diagrid structural typology has its origin at the crossroads of architecture and engineering and has proved to be extremely compliant in structuring broad range of building forms and spans. The early applications of diagrid systems have not focused on exploring its potentials so much, hence a need for this issue is thus created. As a fact, buildings with regular geometry, evenly spread mass and stiffness in both plan and elevation; undergo lesser damage than buildings having irregular geometry.

The diagrid module angle is a criterion which largely affects the structural performance, so under moderate to extreme earthquakes a characteristic seismic force battling system needs to be able to provide sufficient energy dissipation and ductility features. Since the existing works has focused only on constant diagonal angle throughout the building elevation a study on the variation in diagonal angle is taken up. In the present study diagrid building models having different variations in diagonal angle in the elevation are studied for their compliancy to fight seismic forces effectively. Models are simulated using ETABS software and analyzed in terms of Displacement, Storey shear, Storey stiffness, Storey drift, and Time period.
