Abstract:
Because of its narrow width and the required resistance against wind forces and earthquakes, the main structural element of the tower is formed by the reinforced concrete core which houses the building services, i.e., elevators, staircases, and lavatories. This cellular core resists all horizontal forces and carries the greater part of the vertical loads. The office section surrounding this core is a composite of structural steel and reinforced concrete to reduce the column sections to a minimum and to achieve rapid construction. The method of analysis of the core is described, as well as the construction procedure which resulted in the construction of one complete floor in 7 working days.
