Study Notes

Cast-Iron Box

Serves as a built-in element in walls to support the ends of girders.
Essential for structural stability in construction.

Chamfered Column

Chamfering reduces ignition risk at corners by creating beveled edges.
Enhances fire safety in structural design.

Conflagration Breeder

Refers to a building or structure that can lead to large-scale fires affecting multiple buildings.
Highlights the importance of fire mitigation strategies in construction planning.

Corbelled

Involves projecting structures from walls supporting overhanging elements like cornices.
Facilitates architectural aesthetics while providing structural support.

Cross-Laminated Timber (CLT)

Constructed by gluing layers of lumber together with each layer oriented perpendicular.
Offers sustainable and strong building materials for modern construction.

Fire Cut

Joists are angled at the ends to allow for safe detachment during a fire.
Prevents upper walls from being dislocated when joists fail, enhancing building integrity during emergencies.

Heavy Timber

Characterized by large-dimension combustible materials combined with fire-resistant exterior walls.
Recognized for durability and resistance to collapse during fire incidents.

Mill

Represents the initial development of heavy timber construction during the Industrial Revolution.
Significant for its role in evolving construction practices and factory designs.

Scuppers

Designed as drainage outlets in walls to prevent water accumulation on flat roofs or floors.
Critical for managing water runoff, protecting structural integrity.

Slow Burning

Describes buildings that can resist rapid fire spread and allow for control before full involvement.
Important feature in fire-resistant design and construction standards.

Type IV

Indicates heavy timber construction, emphasizing the use of combustible materials with protective features.
Offers a blend of aesthetic appeal and structural performance in building design.
