Wilshire Grand: LA’s Tallest Skyscraper and the Future of Seismic Engineering
The Wilshire Grand Center stands as a towering symbol of innovation, closely eclipsing the U.S. Bank Tower as the tallest skyscraper in Los Angeles. But beyond its impressive 1,100-foot height, this skyscraper represents a leap in engineering, seismic resilience, and construction design—concepts that don’t just apply to high-rises but to buildings across LA, including residential and commercial properties that need seismic retrofitting and foundation reinforcement.
How Was the Wilshire Grand Designed to Handle Earthquakes?
Los Angeles is built on a seismic hot zone, making earthquake resistance a necessity. The Wilshire Grand’s engineers took a revolutionary approach to ensure it could withstand powerful ground movement. Instead of a traditional steel frame, the tower relies on a reinforced concrete core—a design that offers greater lateral stability during earthquakes. The foundation sits atop base isolators, allowing the building to flex and absorb seismic shock rather than transferring it directly to the structure.
This same principle—strengthening foundations, reinforcing structural integrity, and improving a building’s flexibility—is exactly what seismic retrofitting achieves for smaller buildings throughout LA. Older soft-story buildings, apartment complexes, and commercial properties can all benefit from similar reinforcement techniques to meet modern seismic safety standards.
What Can LA Property Owners Learn from the Wilshire Grand?
The Wilshire Grand isn’t just an architectural marvel—it’s a case study in how to future-proof a building against earthquakes. While most homes and commercial buildings aren’t 73 stories high, the lessons from this project apply at every level.
- Foundation Stability Matters – The Wilshire Grand’s deep-set concrete core and seismic isolators prevent catastrophic failure. Homeowners can achieve similar results through foundation bolting, underpinning, and retrofitting.
- Earthquake-Resistant Materials Save Lives – Reinforced concrete and flexible steel frames are designed to absorb seismic shock instead of crumbling. For older buildings, shear wall installation and steel bracing add much-needed stability.
- Seismic Upgrades Aren’t Just for Skyscrapers – Soft-story buildings and homes built before 1978’s stricter building codes are particularly vulnerable. Retrofitting ensures compliance with LA’s Soft Story Retrofit Program (Ordinance 183893) and protects investments from earthquake damage.
Could the Wilshire Grand’s Glass Facade Be a Problem?
Despite its engineering triumphs, not every aspect of the Wilshire Grand has been without controversy. The building’s shimmering facade, made from VRE 1-38 glass, has drawn comparisons to the infamous Vdara Hotel in Las Vegas, where reflected sunlight reportedly caused intense heat beams capable of melting plastic cups.
While experts have downplayed the severity of potential glare issues from the Wilshire Grand, this highlights the importance of proper materials selection in construction—whether for skyscrapers or residential homes. In seismic retrofitting, choosing the right materials for wall bracing, foundation reinforcement, and exterior finishes ensures long-term durability and safety.
Building the Future: How the Wilshire Grand Sets the Standard for LA Construction
Los Angeles is evolving, and as more high-rises push architectural boundaries, seismic safety and foundation integrity remain at the forefront of construction priorities. The Wilshire Grand’s engineering principles can be applied at every level—from towering skyscrapers to single-family homes.
