What is a diaphragm in structural engineering?
Answer: A horizontal structural element (floor or roof) that distributes lateral forces to vertical elements
A diaphragm is a horizontal structural element (floor or roof deck) that collects and distributes lateral loads to shear walls or frames.
The 'slenderness ratio' of a column affects its susceptibility to:
Answer: Buckling
The slenderness ratio (effective length divided by radius of gyration) determines whether a column will buckle before reaching its compressive strength.
Which structural system uses cables in tension to support a roof or large span?
Answer: Suspension structure
Suspension structures support loads through cables working in pure tension, allowing very long spans with minimal material.
In wood construction, what is 'blocking' used for?
Answer: Providing lateral support, transferring loads, and providing nailing surfaces
Blocking consists of short pieces of framing lumber installed between studs or joists to provide lateral bracing, load transfer, and backing for finish elements.
A two-way slab system differs from a one-way slab in that:
Answer: It spans in two directions and is supported on all four sides
A two-way slab distributes loads in both directions to supports on all four sides, which is efficient when the slab's aspect ratio is close to 1:1.
What is the purpose of expansion joints in large buildings?
Answer: To accommodate thermal expansion and contraction and prevent structural damage
Expansion joints divide a building into segments, allowing each section to move independently due to thermal changes without causing cracking or distress.
