A Redefined Skyline For California's Largest City
The tallest building in the Western United States, the 1,100-foot Wilshire Grand has completely redefined the Los Angeles skyline. The 73-story tower houses a four-star hotel, offices, retail space and parking as well as an upscale rooftop “sky lobby” provides guests with sweeping views of Los Angeles that extend to Santa Monica.
We provided structural design and performance-based design services to AC Martin Partners and Brandow & Johnston for the tower, which opened in 2017.
- The tower’s superstructure lateral system consists of a nearly rectangular four-cell cast-in-place reinforced concrete shear wall system.
- We applied performance-based design principles and nonlinear response history analyses to guide the design, validate the tower’s seismic performance, and eliminate prescriptive perimeter moment frames.
- Contracted by AC Martin Partners, we synchronized slab and façade geometry between the architect’s Rhino and Revit models and used the combined data to generate two Revit models.
