wood vs. steel: making the right choice for your building

Wood vs. Steel: Making the Right Choice for Your Building

Choosing between wood and steel for your next project isn’t just a material decision—it’s a balancing act of strength, cost, sustainability, and performance. As structural engineers, we know there’s no one-size-fits-all answer. But with the right tools (like RISA), you can model, compare, and optimize your designs with confidence. So, let’s break it down: wood vs. steel—how do they stack up?

Strength & Performance: The Heavy Hitters

Both materials are powerhouses in their own right, but their strengths shine in different scenarios:

  • Wood – Lightweight yet incredibly strong, wood is the go-to for low- to mid-rise buildings. Mass timber products like CLT (Cross-Laminated Timber) push the limits even further, allowing for taller structures while offering fire resistance and sustainability.

  • Steel – Need long spans, high loads, or extreme durability? Steel is your best friend. Its superior strength and ductility make it the material of choice for high-rises and structures in seismic or high-wind zones.

📊 How RISA Helps: Whether it’s checking lateral loads in a steel frame with RISA-3D or optimizing wood shear walls in RISAFloor, you can analyze every aspect of your structure before the first beam is placed.

Cost & Sustainability: Budget vs. Carbon Footprint

  • Wood – Generally more affordable, especially for small- to mid-size projects. Plus, it's renewable, has a lower carbon footprint, and can contribute to LEED certification. However, moisture and fire protection measures add costs.

  • Steel – Higher upfront cost, but long-term durability, prefabrication efficiency, and recyclability make it a smart investment. Steel also allows for faster construction, saving time (and money) on-site.

📊 How RISA Helps: Optimize material usage, reduce waste, and weigh cost vs. performance in real-time with RISA’s powerful modeling tools.

Fire, Moisture & Seismic: Facing the Elements

  • 🔥 Fire Resistance – Steel holds up well, but without fireproofing, high temperatures can weaken it. Wood, on the other hand, chars predictably, and engineered wood products can achieve impressive fire ratings.

  • 🌧 Moisture & Durability – Wood needs careful detailing to avoid rot, while steel is vulnerable to corrosion. Proper design detailing (which RISA can help model) is key to longevity.

  • 🌍 Seismic Performance – Steel’s ductility makes it a seismic superstar, but wood-framed structures, when designed correctly, can also perform exceptionally well in earthquakes.

📊 How RISA Helps: Model seismic and wind forces, check fire-resistant assemblies, and ensure compliance with code requirements—all before construction begins.

So, Wood or Steel? RISA Helps You Decide

The best material? It depends on your project’s needs, budget, and performance goals. The good news? You don’t have to guess. RISA gives you the power to analyze, compare, and refine your designs—so you can make the right call every time.
