Challenges:The tapered form of the tower and the irregular floor plan presented one of the largest structural design challenges of the project. At its widest section, the top of the tower is 30 feet wider than the base. For maximum program efficiency, the exterior columns were designed to slope with the building taper.
Additional challenges included an aggressive construction schedule and a performance-based design without the benefit of any prior design precedence for a structural system of this type.
Solution:NYA proposed the idea of using steel-plate shear walls instead of concrete shear walls. The idea was implemented, and L.A. Live became the very first steel-plate shear wall high-rise building in L.A.! Using steel-plate shear walls significantly decreased the construction costs, minimized the construction schedule and conserved space in the hotel, thereby allowing more sellable floor area for ownership.
Other notable aspects of the solution included the architect’s vision being uncompromised, early structural completion and the building weight being lighter because of the use of steel-plate shear walls, thereby reducing foundation pressures.
This building has been accredited LEED Silver.
