Tall Buildings - Core Design

Tall Buildings - Core Design Dr. Yasser Mahgoub

Introduction High-rise commercial buildings are the icons of modern society.

These symbolize the power of commerce in the present world system.

They also add the 3rd dimension to the city.

In addition, at the micro level, having an office at an attractive high-rise building gives additional advantage to the business in terms of better customer confidence and corporate identity.

Definition A high-rise building is defined as a building 35 meters or greater in height.

Generally constructed using a structural frame, provided with high-speed elevators.

Rules of thumb There are rules of thumb to determine the number of elevators required for Office buildings: â—? One elevator is required for every 45,000 net usable square feet (4180.64 m2).

â—? The ratio of the number of floors to the number of elevators should be two to one (2:1) or two and a half to one (2.5:1), depending on the occupancy of the building. The more dense the population, the more elevators needed.

Rules of thumb â—? The number of elevators in a single group should not exceed eight (8) and no single group should serve more than (16) levels.

â—? If you have 32 floors, you will need 2 groups of elevators, each group of 8 elevators will serve 16 floors. There should be a service floor at level 16 that connects the two groups together.

Rules of thumb â—? In buildings of four to eight floors, a separate service elevator should be considered. Over nine floors, a service elevator is virtually required.

â—? Upper-floor, special-use areas, such as cafeterias, mail rooms, transfer bridges, etc., can increase the required number of elevators.
