Chapter 4 Test Study Guide

The following key terms and concepts should be reviewed prior to the test on:

Wednesday October 28th.

Section 4.1 Classification of Structures

1. Form and function
2. Ergonomic design
3. The 3 way to classify structures: form, function, construction
4. The 3 structural forms: frame, solid, shell (many structures are combination structures)

Section 4.2 Forces That Can Act on Structures

5. Internal forces: tension, compression, shear, torsion, (bending - combining tension and compression)
6. External forces: gravity, wind, cars, etc.
7. Describing forces: magnitude, direction, point and plane of application
8. Loads: total load, static load, dynamic load
9. Designing for forces: structures must support total load, a 100-year storm

Section 4.3 Designing for Safety

10. Risk Management:ignore the risk, avoid the risk, design for the risk
11. Designing for Loads: Engineers design for the more than the largest possible load
12. Designing for Safety: Ontario Building Code, Ontario Fire Code
13.Designing for Efficiency: What makes a structure efficient?
14. Sensors: Where are they used? How do they make people safe?
