A TYPE 1 building that has elevators and stairs in the middle of the building is categorized as which layout?

• A. Center hallway
• B. Combination
• C. Center core
• D. Atrium

Answer: (C)

Placing elevators and stairs in the middle creates a central core that organizes the floor around that core. This central core is the defining feature of a center core layout, commonly used in high-rise Type I buildings to provide a protected, efficient egress path and strong floor-to-floor organization. A center hallway layout would emphasize a long corridor through the middle rather than a concentrated set of vertical shafts; an atrium describes a large open void rather than a defined core; a combination mixes elements without a single, dominant central core. So the arrangement described best fits a center core.
