Alignment Special Structures for Vancouver's ALRT

by Brian E. Garrett, ABAM Engineers Inc, WA, USA,

Document Type: Proceeding Paper

Part of: Automated People Movers: Engineering and Management in Major Activity Centers

Abstract:

This paper describes the special long-span structures, offset columns, and bent structures used in situations where the standardized guideway components used in over 90 percent of the guideway were inappropriate. The long-span structure consists of a three-span structure arranged so that the precast center span beams are cantilivered over the interior columns and are post-tensioned together in a cast-in-place crosshead. Offset column design solutions are presented for column centerline to guideway beam centerline offsets up to 5 meters, utilizing post-tensioned columns and crossheads. Bent structures, which span a roadway or other obstruction to support the guideway, are post-tensioned to optimize the section depth of the bent girder.
