Overview

One-of-a-kind damper was adopted to withstand the height and wind horizontal loads while enabling the asymmetrical design of the building.

Basic information (construction date, number of stories, gross floor area, adopted design code, engineer(s), Contractor(s), etc.)

Construction date: 2008
Number of stories: 60
Gross floor area: 144,539m2
Adopted design code: IBC; Philadelphia Building Code; LEED 2009
Engineer(s): Thornton Tomasetti
Contractor(s): LF Driscoll

Issue and/or innovation

The building structure had to enable the asymmetrical design. The building uses a central structural concrete core and steel-framed floors. To avoid swaying, the building employs a double-chambered, concrete, 300,000 gallon liquid-tuned column damper, the largest of its kind in all of North America. Lightweight concrete (LWC) was utilized in the composite floor decks.

Reason for composite solution

To withstand the height and wind horizontal loads while enabling the asymmetrical design of the building.

Specific solution/technical details

Structural concrete core with steel-framed floors and columns.

A unique system of beams linked to a core shear wall, and exterior bundled columns were adopted to support the height of the building (it was the tallest composite building in the world when it was completed in 1980) and address various structural challenges, such as the natural tendency of the tube perimeter frame to warp.
