🌲 Myth: Timber buildings are unsafe and weak.
🌳 Facts in a nutshell:
- Timber has one of the best strength-to-weight ratios among all materials.
- Fully standardized and strength classified mass timber elements allow for safe construction of even high-rise buildings.
🏗️ Timber Myth Discussion:
When it comes to building quality and performance, there are two different approaches preferred by members of the steering group: a purist approach and a pragmatic approach.
🌿 The purist approach advocates for exclusive design and construction with biobased materials, aiming to phase out abiotic materials like concrete and steel. It suggests exploring alternatives like carving stone for foundations and cores. However, for high-rise buildings, concrete might be the ideal solution due to multiple factors like weight, height demands, and efficiency.
💼 The pragmatic approach suggests embracing hybrid building systems, where traditional materials like concrete and steel complement timber and biobased materials. This approach requires careful design to ensure that materials from the techno-cycle and bio-cycle are not mixed.
🏙️ Understanding the right use of wood is crucial, where it brings value and makes sense in building construction. Evaluating where timber is suitable and where other traditional bio-based materials should be used is essential for city planning.
🌳 Wood is a natural and anisotropic material, meaning its strength varies according to the direction of loading. However, with strength grading following standards like EN 14081 and classification in strength classes based on EN 338, the non-uniformity of timber can be addressed. Each board intended for structural use undergoes grading to ensure its suitability.
🔬 Engineered timber, thanks to its lightweight and high strength, is considered one of the most efficient building materials available globally from a structural perspective. It easily meets European building regulation requirements with its mechanical properties, such as strength and stiffness.
📐 Strength grading, often performed using laser technology, ensures the quality and structural integrity of incoming timber boards, as seen in the CLT factory of DERIX.
