Cantilever Shell Structures Quiz

Barrel vaults are used when high structural efficiency is required.

Shell structures can only be made with precast panels.

Arch structures are mainly made of fabric materials.

Folded plates have a shell thickness of 80 mm on average.

Portal frames have a span-to-depth ratio that varies from 1:10 to 1:15.

Barrel vaults are a type of thin-shell roof structure.

Shell structures with a span of 50-150 meters can be made out of reinforced concrete.

The usual span-to-depth ratio for shell structures ranges from 1:10 to 1:15.

Reinforced concrete folded plates have a slope range of 50° to 75°.

Arch structures are less efficient because they do not entirely rely on compression forces.

Barrel vaults provide long uncluttered spans, comparable to truss-framed roofing systems.

Folded plates in reinforced concrete shells have an average shell thickness of about 100 mm.

In post and beam structures, the column cross-sectional area should not be less than 30 cm.

The beam depth in a shear wall can reach up to 2 meters.

Barrel vaults are very lightweight structures with vaulted and dome shapes.

Shell structures have little tensile capacity and are made of materials like masonry and unreinforced concrete.

Portal frames consist of vertical columns, beams, and columns that support floor slabs and roof cladding.

Arch structures can be built with reinforced concrete for spans up to 60 meters.
