Structural Engineering White Paper: Edmonton Clinic South
With a footprint of approximately 7,000 sq. m., the Edmonton Clinic South comprises one basement level and seven floors above ground, plus a two-storey mechanical penthouse. The main architectural feature of the Edmonton Clinic South is a curving, eight-storey glazed atrium wall on its east elevation. The atrium wall is 37m high and has a 60m arc length, divided into a two-storey curtain wall portion from the ground to the third floor and a clamped point-supported glazing wall portion from the third floor to the roof. The point-supported glass panels span vertically between square HSS girts. In turn, the girts are supported by round HSS356 columns that carry the atrium roof and act as the compression member of a double- cable truss system. The geometry of both cables approximates a parabola. The trusses are spaced at 7.8m and span from the top of a curved horizontal arch-truss to the roof, a height of almost 30m. This paper explains the structural behaviour of the atrium wall cable truss system and how the individual components interact. Challenges encountered during design, fabrication, and erection are outlined. Particular focus is put on the three-dimensional aspects of the design, including stability considerations. The paper also addresses the significance of a constructive collaboration between all parties that led to the successful completion of this new Edmonton landmark, being to the authors’ knowledge the largest of its kind in Canada.
