Structural Wood Design
Structural Engineering Wood Design
Wood has long been recognized for its versatility in construction, but in recent years, advancements in structural engineering have propelled wood into a new realm of architectural possibilities. At HECO Engineers, we embrace wood as a primary material for various design applications, leveraging its unique properties to create sustainable, cost-effective, and resilient structures.
The Case for Wood in Structural Engineering
Wood is one of the oldest construction materials, valued for its availability and ease of use. In modern engineering, wood has evolved into a high-performance material thanks to innovations such as mass timber, cross-laminated timber (CLT), and advanced wood framing techniques. These innovations have expanded wood’s role from single-family homes to mid-rise commercial buildings, sports arenas, and even multi-story urban towers. The growing demand for sustainable design and environmentally conscious construction has made wood an increasingly attractive option for structural engineers and architects alike.
Some of the key benefits that wood offers include:
-
-
- Sustainability: As a renewable resource, wood’s production and processing have a much lower environmental impact compared to steel or concrete. Wood stores carbon dioxide, making it a climate-friendly material when sourced responsibly from managed forests.
- Strength-to-Weight Ratio: Wood’s impressive strength-to-weight ratio allows for creative and efficient design solutions. Compared to heavier materials like concrete and steel, wood reduces the demand for heavy foundations, lowering costs.
- Aesthetic Appeal: Beyond its structural capabilities, wood is prized for its aesthetic qualities. Its natural grain and texture bring warmth to both interior and exterior spaces, providing a design element that other materials can’t replicate.

Wood Design Techniques and Innovations
In structural engineering, the use of wood has been revolutionized by modern design methodologies and technologies. Here are some of the innovations that have shaped the field of wood design:
Mass Timber Construction
Mass timber refers to large, solid wood panels used in floors, walls, and roofs. Mass timber buildings can be built faster than those using steel or concrete, while providing similar strength and fire resistance.
Cross-Laminated Timber (CLT)
CLT is a type of mass timber composed of layers of wood stacked perpendicularly and glued together. This technique enhances the strength and stiffness of wood, making it suitable for tall buildings, seismic regions, and other high-stress environments. CLT is fire-resistant and provides excellent acoustic performance, making it ideal for residential and commercial spaces.
Glue-Laminated Timber (Glulam)
Glulam beams are made by gluing layers of dimensional timber to create strong, structural elements that can be used in large-span designs like sports arenas or bridges. Glulam is both strong and flexible, offering unique design possibilities, particularly for long, curved spans.
Advanced Wood Connectors:
Modern wood design also benefits from innovative connectors that improve the structural integrity of wood systems. These include metal plates, fasteners, and brackets specifically designed for wood construction, ensuring strong and reliable connections between structural components.
Wood’s Role in Sustainable and Resilient Design
Sustainability is a critical factor in modern building practices, and wood stands out as a key material in the pursuit of environmentally responsible construction.
Wood-based construction is compatible with green building certifications like LEED (Leadership in Energy and Environmental Design), helping project developers achieve sustainability goals. At HECO Engineers, we prioritize sustainability by incorporating advanced wood materials and technologies into our designs, particularly for projects seeking to minimize their environmental impact.
Wood also plays a significant role in resilient design, particularly in regions prone to seismic activity. Wood structures have an inherent flexibility that allows them to absorb and dissipate seismic energy, reducing the risk of catastrophic failure during earthquakes. Innovations in shear walls, diaphragms, and other lateral-force-resisting systems have further enhanced the performance of wood in seismic conditions.
Structural Wood Design Best Practices
Designing wood structures requires a deep understanding of material behavior under various conditions, including load, moisture, and temperature. At HECO Engineers, we follow several best practices to ensure that our wood designs meet both performance and safety standards:
-
-
-
Moisture Control: One of the most critical considerations in wood design is moisture management. Wood’s properties change significantly with moisture content, so it’s essential to protect wood components from prolonged exposure to moisture through proper detailing, ventilation, and moisture barriers.
-
Fire Safety: Modern wood buildings must meet stringent fire safety requirements. Wood’s charring behavior provides a predictable response to fire, allowing structural engineers to design with fire resistance in mind. The use of fire-retardant treatments and fire-resistant wood materials ensures compliance with building codes.
-
Acoustic Performance: In commercial and multi-family residential buildings, sound insulation is crucial. HECO Engineers incorporates sound-absorbing materials into wood designs, where acoustic control can be more challenging due to the stiffness and density of wood.
-
Energy Efficiency: Wood’s natural insulating properties make it a key material in energy-efficient design. HECO Engineers uses wood to reduce thermal bridging in building envelopes, ensuring that our structures perform well in terms of energy conservation.
