ExAC - Theme 3: Coordinating
Engineering Systems Exam Questions &
Answers (Grade A+)
Principles of a Structural System -
correct answer ✅- Designed and constructed to support and
transfer loads safely to the ground without exceeding allowable
stresses in each member.
- Strive for a state of equilibrium
- Free Body Diagram (FBD) illustrates forces acting and reacting to
structural loading


Identify types of Static Loads -
correct answer ✅Applied slowly to the structure without rapid
fluctuation:
- Dead Load (weight of structure and materials)
- Live Load (moving or movable loads from occupancy)
- Snow Load (weight of snow on a structure)
- Settlement Load (structure settling on ground pressure)
- Hydrostatic Load (pressure from water on the foundation)

Main elements of a Structural System -
correct answer ✅Substructure (Foundation)
- Anchors superstructure and transfer loads to ground
- Distributes loads evenly throughout supporting earth
Superstructure (Framing)
- Vertical extension of a building above foundations
- Comprised of columns, beams, slabs, bearing walls and roof
structures
