Function
A mixed-use tall building contains two or more functions (or uses), where each of the functions occupy a significant proportion of the tower's total space. Support areas such as car parks and mechanical plant space do not constitute mixed-use functions. Functions are denoted on CTBUH "Tallest Building" lists in descending order, e.g., "hotel/office" indicates hotel function above office function.
residential / hotel
Structural Material
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from steel. Note that a building of steel construction with a floor system of concrete planks or concrete slab on top of steel beams is still considered a “steel” structure as the concrete elements are not acting as the primary structure.
Reinforced Concrete
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from concrete which has been cast in place and utilizes steel reinforcement bars.
Precast Concrete
Both the main vertical/lateral structural elements and the floor spanning system are constructed from steel reinforced concrete which has been precast as individual components and assembled together on-site.
Mixed-Structure
Utilizes distinct systems (e.g. steel, concrete, timber), one on top of the other. For example, a steel/concrete indicates a steel structural system located on top of a concrete structural system, with the opposite true of concrete/steel.
Composite
A combination of materials (e.g. steel, concrete, timber) are used together in the main structural elements. Examples include buildings which utilize: steel columns with a floor system of reinforced concrete beams; a steel frame system with a concrete core; concrete-encased steel columns; concrete-filled steel tubes; etc. Where known, the CTBUH database breaks out the materials used in a composite building’s core, columns, and floor spanning separately.

About The Ritz-Carlton Los Angeles
LA Live is the first high-rise to be built in Downtown Los Angeles in 20 years, making it the first building to have a significant impact on the skyline in the same period. LA Live and its distinctive tower fill a long-standing void in the southwest corner of the downtown area as bounded by the cornerstones of the Disney Concert Hall, Los Angeles City Hall and the financial, garment and jewelry districts.
The building expands horizontally as it rises vertically, reflecting the varied programs within. Each succeeding use—22 JW Marriott Los Angeles at LA Live floors at the bottom, followed by four floors of The Ritz-Carlton Hotel Los Angeles, and the Ritz-Carlton Residences at the top—has larger space requirements. The building’s elegantly curving curtain wall smoothes the jagged transition among the changing floor plates as they stack skyward.
The three-story lobby is a pass-through space that provides access from Olympic Boulevard to the Nokia Theatre and Nokia Plaza. The lobby is the urban connection between Downtown and LA Live, the Staples Center and Los Angeles Convention Center. The building features two outdoor decks with pools, bars and events facilities.
The tower takes full advantage of a new leading edge Performance Based structural steel lateral force resisting system, comprised of un-stiffened thin steel plate shear walls (SPSW). It is the first high-rise to use this technology in California. Using 6.4-9.5mm (0.25-0.375in) thick steel plate shear walls as opposed to 76cm (30in) thick concrete columns created increased usable square footage, and creating a lighter building allowed the addition of four floors to the tower while creating better views on every floor without the necessary moment frames common in steel design. Switching to Steel Plate Shear Walls also saved millions of dollars in construction costs and shaved four months off the production schedule. The hotel tower also consists of steel moment frames, Buckling Restrained Braces (BRB), mid-height outriggers and cap trusses. The design process exemplifies a successful collaboration of performance-based engineering and rigorous peer review by a panel of noted experts in each structural system type.
