Types Space frame

this train station supported barrel vaults structure.



barrel vaults. type of vault has cross section of simple arch. type of space frame not need use tetrahedral modules or pyramids part of backing.
spherical domes , other compound curves require use of tetrahedral modules or pyramids , additional support skin.

classification arrangement of elements

single layer grid. elements located on surface approximated.
double layer grid. elements organized in 2 layers parallel each other @ distance apart. each of layers form lattice of triangles, squares or hexagons in projection of nodes in layer may overlap or displaced relative each other. diagonal bars connect nodes of both layers in different directions in space. in type of meshes, elements associated 3 groups: upper cordon, cordon , cordon lower diagonal.
triple layer grid. elements placed in 3 parallel layers, linked diagonals. flat.

other examples attach definition of space frame these:

pleated metallic structures. emerged try solve problems formwork , pouring concrete had counterparts. typically run welded joint, may raise prefabricated joints, fact makes them space meshes.
hanging covers. designs on cable taut, spine, , catenary arch antifunicular show ability channel forces theoretically better other alternative, have infinite range of possibilities composition , adaptability type of plant cover or ensure vain. however, imprecisions in shape having loaded strand (ideally adapts dynamically state of charge) , risk of bending arc unexpected stresses problems require pre-compression , prestressing elements. although in cases tend cheapest , technical solution best fits acoustics , ventilation of covered enclosure, vulnerable vibration.


the dome ‘parashell’ concrete structure , 1 in scotland. constructed using pioneering technique in concrete poured onto special neoprene membrane , pneumatically inflated.



pneumatic structures. wherein closure membrane subjected pressurized state, may considered within group.
