Large span structure is very common these days. These include rigid element structures, suspension structures, stayed structures and pneumatic structures reinforced by cables. The distribution for these structures is chosen according to the main load carrying elements. According to this property, there are four kinds of structures.
- Structures with rigid members.
- Suspension structures.
- Stayed structures.
- Pneumatic structures with ropes.
- Plate Girder.
- Truss and lattice girder.
- Arch.
- Frame.
- Stayed structure.
- Suspension structure.
- Structures with rigid members
- Plate girder
- Truss
- Arches
- Suspension structures
- They are of two types.
- Cable structures.
- Membrane structures.
- Advantage of this structure includesthe fact that this structure needs very less material usage and has great shape possibilities
- Stayed structures
- The stays create extra support. They are of two types
- Stiff.
- Flexible.
