Study Notes
Heavy Timber Construction Characteristics
- Heavy Timber Construction utilizes large, solid wood beams and columns for structural integrity.
- Fire resistance is achieved as thick wood members char on the outside, creating an insulating barrier for the interior.
Mill Construction Specifics
- Distinguished from Heavy Timber Construction by the use of non-combustible exterior walls.
- Incorporates thick, solid wood floors and large timber beams alongside non-combustible materials.
Environmental Benefits
- Heavy Timber is considered environmentally friendly due to wood being a renewable resource.
Challenges
- Requires regular maintenance to prevent moisture intrusion and potential fire hazards.
- Modifications to old Heavy Timber buildings can compromise fire resistance, especially when unprotected steel is involved.
Structural Components
- Beams serve as horizontal structural members supporting roofs and floors.
- Columns are vertical members carrying load from beams to the foundation.
Fire Resistance
- Non-combustible materials in Mill Construction prevent ignition during fire exposure.
- "Char" formation on large timbers acts as a protective layer, preserving the core from combustion.
Significant Terminology
- "Conflagration Breeders" refer to structures that may initiate large, uncontrollable fires.
- "Delamination" in Cross-Laminated Timber (CLT) can weaken the structure during a fire.
Modern Engineering
- Engineered wood products have enhanced strength and stability compared to solid wood.
- Mass Plywood Panels (MPP) consist of layers of wood veneers bonded together, used in taller structures.
Safety Measures
- Functional sprinkler systems are critical for quick fire control and preventing large-scale fires.
- Fire Cut Girders in Mill Construction prevent walls from collapsing if girders fail.
Code and Regulation
- New Type IV-A construction codes permit up to 18 stories with mass timber covered in gypsum board for enhanced fire safety.
- Minimum wood column dimensions in Heavy Timber buildings are 8 inches in any dimension, with specific sizes for supporting loads.
Emergency Preparedness
- Prefire planning is essential for determining effective firefighting strategies and resource allocation.
- Caution is necessary during firefighting in modified Heavy Timber buildings due to the risk of unprotected steel elements.
Case Studies
- The Worcester Cold Storage Fire highlighted the need for effective fire prevention measures in vacant heavy timber buildings.
Key Points on Fire Hazards
- Concealed spaces in modern renovations can allow undetected fire spread, raising safety concerns.
- Vacant Heavy Timber buildings without proper fire barriers can experience rapid fire propagation.
