CEA Semester 2 Final Review
Exam Questions and Answers
The primary function of a building structure is - -to support and transmit the
building loads and forces to the ground.
- Structural System is made up of what? - -many smaller structural sub-
systems that work together to provide a strong, stable, and cost-effective
structure
- Examples of smaller structural sub-systems: - -roof, walls, floors, framing,
foundations
- who designs things like roofs, walls, floors, framing, and foundations? - -
structural engineers
- What are structural sub-systems made out of? - -many structural elements
that work together to provide a strong, stable, and cost-effective system.
- Basic structural elements include: - -beam, column, truss, arch, vault,
dome
- Who designs structural sub-systems? - -Structural Engineers
- What is force? - -any action that causes a change in the shape or motion
of an object
- Load - -a force that is supported by a structural element.
- Are the terms force and load are often used interchangeably? - -Yes
- What are the structural member forces? - -tension, compression, shear
- tension - -A force that stretches or pulls apart a member, resulting in the
member elongating
- Compression - -A force that squeezes or presses a member together,
resulting in the member shortening.
A force that squeezes or presses a member together, resulting in the
member shortening.
- Shear - -A force that acts perpendicular to the axis of the member,
causing the internal particles of the member to slide against each other.
, - What is a beam? - -A structural element that carries a load that is applied
transverse (perpendicular) to its length.Usually a horizontal member that
carries a vertical applied load.
- The top fibers of a beam are in _______________. - -compression
- The bottom fibers of a beam are in __________. - -tension
- What is a cantilever beam? - -A special type of beam that is supported
only at one end.
- The top fibers of the cantilever are in _________. - -tension
- The bottom fibers of the cantilever are in _______________. - -compression
- What is a column? - -a vertical structural element that carries an axial
force in compression.
- What is a truss? - -A structural element that is composed of smaller
structural members typically configured in triangular arrangements
- Some truss members carry a tension force; others carry a ______________
force. - -compression
- What is an arch? - -A curved structural element that spans over an open
space.
- In stone arches, the last stone to be placed at the top is called the
____________. - -keystone
- What is a vault? - -A continuous arch that forms a ceiling or roof.
- What is a dome? - -A structural element that is made up of arches that
radiate around a center point to create a half sphere.
- How many hybrid forms - -An infinite number of combinations of these
forms exist.
- The same _________ ___________ used by engineers and designers in other
disciplines can be used to design structural systems. - -design process
- What are the steps in the design process? - -1. Define the problem
2. Generate Concepts
3. Develop a solution
4. Construct and test prototype
5. Evaluate Solution
