EXAC - THEME 3 COORDINATING
ENGINEERING SYSTEMS EXAM (Latest
Update ) Questions & Answers
100% Correct - (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)
Identify types of Dynamic Loads - correct answer Applied suddenly to a building with
rapid changes:
- Wind Load (exerted by kinetic energy of moving air mass)
- Seismic Load (earthquake waves on a structure)
, 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
Types of Excavations - correct answer - Soldier Piles & Lagging
- Sheet Piling
- Tie-backs
- Slurry Wall
- Dewatering
Elements of Superstructure - correct answer Columns
- Support axial compressive loads applied to the ends of the members
- Wood, masonry, concrete, steel
- Can fail due to compressive forces exceeding load bearing capacity
Beams
- Transfers loads horizontally to vertical supports
- Deflection occurs when bending moment is opposite to resisting moment
- Efficiency is increased when deeper members to minimize bending stress
Trusses
- Structural frame based on rigidity of triangular shape
- Top and bottom chords help distribute forces along web members
