Top 5 Ways Engineers “Earthquake Proof” Buildings - Explained by a Structural Engineer
Mat Picardal・6 minutes read
Structural engineers design buildings to withstand earthquakes and ensure safe evacuation, utilizing moment frames, bracing systems, and shear wall systems to strengthen weak connections, absorb forces, and prevent shearing off the foundation post-earthquake.
Insights
- Structural Engineers focus on designing buildings to withstand earthquakes rather than making them completely earthquake-proof, prioritizing safe evacuation post-earthquake, similar to surviving a car accident.
- Moment frames, bracing systems, and shear wall systems are crucial components in earthquake-resistant building design, each serving a specific function in strengthening weak connections, absorbing forces, and preventing shearing off the foundation, respectively, showcasing the complexity and considerations involved in structural engineering for seismic events.

Earthquake-resistant building design for safe evacuation.
- Structural Engineers design buildings to resist earthquakes, not make them earthquake-proof, ensuring safe evacuation post-earthquake, akin to surviving a car accident.
- Moment frames, like heavily welded or bolted joints, strengthen weak connections in non-engineered buildings, though they can wobble and deform during earthquakes.
- Bracing systems, stiff and strong, brace buildings during earthquakes, designed as the building's fuse to absorb earthquake forces without damaging crucial structural elements.
- Shear Wall Systems, essential for concrete and wood buildings, prevent shearing off the foundation during earthquakes, being the strongest and stiffest structural systems, albeit disliked by architects for their wall-like appearance.
