Curved directly glazed steel structure - the new departure station, E-Line, The Hague

ZJA Zwarts & Jansma Architects have designed a new light rail departure station in The Hague, The Netherlands. The spatial roof structure of the station is made of rolled steel rectangular hollow sections arranged in two independent layers rigidly connected to each other. A glass envelope covering the roof structure matches the contours of the steel exactly. Since the diamond-shaped glass panes could only be attached to the outer layer of the steel grid, the panes (with edge lengths of approx. 1.30 m) are supported on two sides only. When optimizing the overall geometry, the double-curvature area at the nose of the roof structure became a special focus. Knippers Helbig Advanced Engineering has managed to minimize the deviation of each single glass pane from the single-curvature geometry to a maximum out-of-plane deformation of only 3 mm. Therefore, the project is a great example of how geometry development can influence structural design and enable new approaches.

The journal Steel Construction

Steel Construction publishes peer reviewed papers covering the entire field of steel construction research. In the interests of “construction without depletion”, it skilfully combines steel with other forms of construction employing concrete, glass, cables and membranes to form integrated steelwork systems.

Since 2010 Steel Construction is the official journal for ECCS- European Convention for Constructional Steelwork members. You will find more information about membership on the ECCS homepage.
