Tubular Structures
Tubular structures are made by hollow sections. By virtue of its shape, Hollow sections have high Radius of Gyration and other properties resulting in savings in Material, Transportation and Fabrication cost.
By virtue of its shape, Hollow sections have higher concentric strength.Due to closeness of the section there will be higher torsional rigidity compared to conventional sections.
- Tubular sections have Better lateral stability and lower wind drag.
- Tubular sections enables weight reduction of upto 30%.
- Tubular structures have Less Surface area compared to equivalent conventional sections results in savings in Paint and Labour cost.Due to less weight and smoother profile, fabrication is easier. Also minimum use of gusset plates expedites the fabrication process.
Due to higher torsional rigidity and better moment resistance on both the axis, bending of hollow section is easier compared to open sections. This gives flexibility to the architects to shape their structures and express their creativity. Smooth profile of Tubular structures enhances the aesthetic appeal of the structures.Most suitable for usage in exposed environment.
