Truss type double layer barrel vault is simple structural formation made up of network of longitudinal, transverse and braced member with curvature in one direction only. The slab type barrel vaults consist of concrete shell supported on longitudinal beam and having curvature in one direction. Both types of barrel vault are analyzed and designed for Aspect Ratio (Rise/Span) with consideration of Loads like Live Load, Dead Load, Wind Load and Load combinations The truss type barrel vault is designed as per IS: 800-2007 and slab type is designed as per IS: 456-2009. This work leads to the comparison on span, maximum deflection, selfweight and cost criterions.

The Double Layer Grid (DLG) is a valuable tool for the architect or engineer in the search for new forms, due to their wide variety and flexibility. DLG is the truss spanning in three directions to cover large spans without intermediate support. Except the planner beams and trusses all other structures are 3D in sense as they have length, depth and thickness. Beams and trusses are predominantly 2D in their actions as they effectively resist loads applied only in one direction between their supports. But from stability point of view third dimension is also important. Hence 3D action is considered. Groups of DLG were made according to the span range from 25 meter to 100 meter with the two different sets of aspect ratio ( )Viz- 0.035 to 0.065 and 0.05 to 0.08 with interval of 0.01. The initial analysis and design work of DLG is carried out on STAAD Pro as per IS 8...
