Abstract: The Washington State Convention and Trade Center is a 10-level, 1,000,000-square foot facility constructed over Interstate 5 in downtown Seattle. The project spans over three city streets in addition to the 12 lanes of the freeway. The structure is framed in structural steel. Sixteen major trusses up to 90 feet in depth carry the gravity loads, as well as wind and earthquake loads. The arrangement of these trusses permitted the development of three levels of parking for 1,000 cars below the exhibition floor. The total cost of the project is 130 million. The paper describes the structural design and construction of the facility.
