Question 1

What is the purpose of a moment frame in structural engineering?

Accepted Answer

To resist lateral loads through rigid beam-column connections

Answer

To resist gravity loads only

Answer

To distribute tributary loads to footings

Answer

To provide a path for vertical loads to skip over openings

Question 2

What does 'tributary area' mean in structural design?

Accepted Answer

The area of floor or roof that contributes loads to a specific structural member

Answer

The total floor area of the building

Answer

The area around a column that must be reinforced for punching shear

Answer

A slab supported directly by columns with no beams or drop panels

Answer

Beams in both directions supporting the slab

Answer

A slab with thickened areas (drop panels) around columns

Answer

A one-way slab spanning between parallel beams

Question 4

In seismic design, the concept of 'base isolation' involves:

Accepted Answer

Placing flexible isolators between the foundation and structure to decouple seismic motion

Answer

Anchoring the building rigidly to the foundation

Answer

Building below grade to avoid surface ground motion

Answer

Stiffening the building to resist seismic forces

Answer

Rigid frame only

Answer

Bearing wall system

Answer

Flat slab without shear walls

Question 6
