Overcoming seismic challenges in the tallest building west of Mississippi

The Wilshire Grand is California’s tallest skyscraper located just 46 miles away from the San Andreas Fault. Needing to withstand earthquakes up to a magnitude of 7.4, the structure had to be dynamic enough to handle environmental forces, but rigid enough to remain comfortable for its visitors.

As a result, the project included a concrete core wall with outriggers and belt trusses for added support. The core’s function was to stabilize the building against both seismic and wind force, as well as anchor structural elements of the build.

  • Resistance to seismic activity and strong winds
  • Accommodating settlement and shrinkage
  • Using the right welding method

The Wilshire Grand project illustrates how planning and designing with constructability in mind is essential for efficient and innovative steel erection.
