Learning objective
Explain structures and materials, reproduce the worked example and justify a decision in the case study.
Before you begin
Plans and elevations
Understand
Loads, span, strength, cost, and availability influence materials and structural systems.
Worked example
A light, well-connected roof can respond differently to wind than a heavy roof.
Analysis and common mistakes
The load path connects roof, beams, columns or walls, foundations and ground. A strong member does not guarantee a safe structure if connections or soil are inadequate.
Case study — reasoning
Trace a roof’s weight to the ground and mark connections. This diagram explains the principle; sizing, wind and seismic design require qualified professionals and applicable codes.
