Abstract

The Rose Theatre in Brampton, Ontario was to be constructed twenty meters away from a CN main railway line (which includes commuter and freight rail traffic) and on top of a pre-existing underground parking garage which was to remain intact and in operation during the course of construction. A full concrete slab could not be supported by the pre-existing parking garage columns; therefore, a transfer grid, designed by the structural engineer, was employed and as a result a typical "room-within-a-room" construction could not be conventionally achieved. Railway airborne noise is controlled to meet the interior objective of RC 20 by providing a "floating" shell enveloping the entire building. Exterior concrete pre-cast panels are resiliently supported and resiliently connected back to the building and the entire roof slab was vibration isolated from the structure. For railway-induced vibration, the building was supported on a transfer grid which was in turn supported by 250 mm thick rubber vibration isolation pads. The entire building, including exterior shell, stairs and elevators is vibration isolated from ground-borne rail vibration. The measured vibration levels (and the noise radiated by vibrating surfaces) in the theatre were controlled to well within the design objective.
