BArch Bachelor of Architecture Structural Systems in Architecture 1

Question 1

Which structural system uses a series of arches to transfer loads laterally to buttresses?

Accepted Answer

Flying buttress system

Answer

Flying buttresses transfer the lateral thrust of vaults and arches to outer piers, a technique perfected in Gothic cathedrals.

Question 2

In a simply supported beam, the maximum bending moment occurs at which location?

Accepted Answer

At the midspan

Answer

For a uniformly distributed load on a simply supported beam, the maximum bending moment occurs at the midspan.

Question 3

A space frame structure primarily resists loads through which mechanism?

Accepted Answer

Axial forces in a three-dimensional network

Answer

Space frames distribute loads through axial tension and compression forces across a three-dimensional triangulated network of members.

Question 4

Which term describes the tendency of a tall building to sway due to wind loads?

Accepted Answer

Lateral drift

Answer

Lateral drift refers to the horizontal displacement of a building under lateral loads such as wind or seismic forces.

Question 5

What is the primary advantage of a post-tensioned concrete slab over a conventionally reinforced slab?

Accepted Answer

Reduced slab thickness and longer spans

Answer

Post-tensioning applies compressive stress to the slab, counteracting tensile stresses and enabling thinner slabs with longer spans.
