PROJECTS > CORPORATE OFFICES/ CAMPUSES > Walt Disney Corp, Riverside Dr. Building & Pedestrian Bridge - Burbank, California
Project Details:Aldo Rossi designed this ten-story, 1.0-million-square-foot, corporate headquarters, with five levels of subterranean parking. The tower portion of the building is steel construction. The lateral systems consist of steel moment frame and interior braced frames. The floor framing consists of composite concrete deck and steel beams. The basement levels are concrete flat-slab construction.
The basement of the building is 20 feet below the water table. Grouted, high-strength steel tendon soil anchors 40 feet in length are used to resist "floating" forces. The optimized office tower is constructed of steel eccentrically braced frames with a steel moment frame dual system.
The intricate pedestrian bridge comprises of 300 feet of curved steel and the concrete composite bridge has four spans; the longest being 80 feet that crosses over a multi-lane Riverside Drive, connecting both campuses. This bridge consists of a floor deck with steel metal with concrete filling and a steel plate roof.
Structural design marries three-dimensional curves with functional and constructability demands. Creative use of material allows composite action between steel plates and concrete walking deck forming a box girder. The bridge structure's overall depth was limited to 33 inches clear spanning over 80 feet across a major roadway. Collaboration with the contractor helped develop a structural design to support construction procedures resulting in reducing the shut-down of Riverside Drive to only a single weekend.
