The basic functional requirements for self-service parking structures -clean traffic flow, protection against obsolescence, gradual slopes and turns, and smooth transitions between changes in slope-are met economically with re-inforced concrete. Cost comparisons are provided for several recently built parking structures. Application of these general requirements is illustrated in the 630-car facility completed in Edmonton, Alberta. One-way traffic flow throughout is facilitated by elongated twin helical ramps nested within one another. A circular express down ramp also makes use of nested helixes. Foundation construction, beam and column design problems, radiant heating in slab, and a structurally separate stair and elevator tower are among building elements highlighted for discussion. A transverse expansion joint dividing the 320 ft long building is described, and structural details incorporated to provide for future expansion to IOOO-car capacity are explained.
