Case Study_David Lawrence Convention Center

Location: Pittsburgh, PA
Size: 1.45 million square feet
Cost: $294 million
Completion Date: September 2003

Inspired by the close suspension bridges, the David L. Lawrence Convention Center is charactereized by its clear-span roof constructed as a cable-stayed structure. The new project combines contemporary design with steel technology, influenced by the urban topography, the city's industrial history, and innovations in steel. Having achieved the USGBC LEED gold rating, the project is just one part of the city's continued emphasis on sustainable design. The facility features the largest column-free space through the investigation in long-span structures. The steel frame consists of major frames to the north and south of the building known as the bow and stern, resembling parts of a ship. The overall design incorporates 15 enormous cables strung over tall masts as seen in an image below.

Tidbit_Steel Innovations

I found a great summary of metal innovations in the book Steel & Beyond, as described on arcspace.com

Recent Advances:
Extremely light alloys
Hybrid constructions
Advanced methods for load calculations
Digital design and fabricataion
Adaptation of techniques from aeroplane design and ship building


It was also interesting to note that the last period of equivalent change occured during the mid 19th century when mass production of iron, steel, and glass developed.
