DTA3.2 — Introduction to structural systems
Design Technology · SL / HL · syllabus-mapped notes
DTA3.2.1
Structures everywhere
Structures are ubiquitous in nature and the built environment.
DTA3.2.2
Classifying structures
Structures can be classified in different ways.
DTA3.2.3
Beams and columns
Structures are often comprised of multiple parts.
DTA3.2.4
Static and dynamic forces
Static and dynamic forces can be identified according to how they act on a structure.
DTA3.2.5
Stress, strain and failure
In structures, it is important to know how and when an object or material will stretch, bend or break.
DTA3.2.6
Young’s Modulus
Materials with differing Young’s Modulus are chosen for specific applications.
DTA3.2.7
Equilibrium and stability
When forces on a structure are in equilibrium, the structure is stable.
DTA3.2.8
Strengthening techniques
The overall design of a structure can be improved by applying strengthening techniques.
DTA3.2.9
Safety factor
Structures are typically designed with a safety factor (SF) in case of overloading.
DTA3.2.10
Designing above the required load
Structures are typically designed to withstand higher loads than required.
