When it comes to buildings and structures, there’s no shortage of misconceptions. Whether it’s fear over small cracks in concrete or the belief that old buildings are always safe, these myths can lead to costly mistakes, unnecessary worries, or worse—actual structural failures.
At Pittsburgh Design & Engineering Services, we believe in empowering our clients and industry partners with accurate knowledge. So today, we’re busting five of the most common structural myths that could be putting your projects—or even your safety—at risk.
Myth #1: "Cracks in Concrete Always Mean Structural Failure"
Reality: Not all cracks are a sign of disaster.
Concrete naturally expands and contracts due to temperature changes, moisture, and settling. Many small cracks are harmless. However, some cracks could be warning signs of deeper structural issues—such as foundation movement or load stress.
When should you worry? Few to mention
Pro Tip: If you’re unsure whether a crack is minor or serious, a professional assessment can save you thousands in repairs by catching issues early also can save you more in possibly unnecessary or incorrect repair when not assessed by the right professional.
Myth #2: "Steel Structures Never Rust"
Reality: Steel is incredibly strong—but not invincible.
Steel is widely used for its strength and durability, but it can rust and then corrode over time if exposed to moisture, and oxygen. Rust weakens steel, leading to reduced load capacity and potential failure.
How do we prevent steel corrosion?
Pro Tip: If you manage a steel-framed building, don’t wait for visible rust! Regular inspections ensure longevity and safety.
Myth #3: "The Stronger the Foundation, the Stronger the Building"
Reality: A strong foundation alone won’t save a structure if the soil beneath it is weak.
A poorly designed foundation on unstable or improperly compacted soil can lead to: Uneven settling; Structural cracks; Building tilting or shifting.
Warning signs of foundation trouble:
Pro Tip: Before construction, soil testing and geotechnical analysis are crucial to designing the right foundation for site-specific conditions. A strong foundation means nothing if it's sitting on weak ground!

Myth #4: "If a Building Has Been Standing for Decades, It Must Be Structurally Sound"
Reality: Longevity does not equal structural integrity.
Just because a building has stood the test of time doesn’t mean it’s safe today. Materials degrade, construction standards evolve, and hidden structural issues can lurk beneath the surface.
Common hidden dangers in aging buildings:
Pro Tip: If your building is 30+ years old, consider a structural assessment to identify any issues before they become too expensive to address and turn into safety hazards. Retrofitting or reinforcing aging buildings can extend their life while maintaining safety and compliance.
Myth #5: "If It Ain't Broke, Don’t Fix It"
Reality: Just because a structure looks fine doesn’t mean it's free from hidden damage.
Many serious structural issues start internally and only become visible after significant damage has occurred. Routine inspections catch problems early, saving time, money, and potential safety risks.
Examples of hidden structural issues:
Pro Tip: Preventative maintenance is always cheaper than emergency repairs. Scheduling routine structural inspections is a smart investment that pays off in long-term stability and safety.
Final Thoughts: Know the Facts, Protect Your Investment
