158 Category 4: Special Projects 4 Support Structure for Glass Roof - Stockholm, Sweden SE Contact Jurn De Vleeschauwer, Steven Nachtergaele Address Grote Baan 18 9920 Lovendegem, Belgium Website www.stendess.com Stendess calculates and draws complex steel constructions in a high quality and efficient manner while seeking economically responsible and substantial solutions for specific technical stability issues. Thanks to the integral service, where the design of the metal superstructure and the concrete substructure are calculated and drawn by experts in the same office, the building owner and principal contractor retain 100% control over the complete structure. References demonstrate the multidisciplinary knowledge and ability of our engineers and designers in the market of bridges, industry, utility and other projects located worldwide. Owner Pembroke Architect Tengbom General Contractor Scheldebouw BV Engineering Office Ingenieursbureau Stendess N.V. Construction Period 01/2014 - 09/2014 This project consists of the design and calculation of a steel support structure for a skylight, spanning an area of 286 m², located on the roof of a building in Stockholm, Sweden. The design of the skylight is conceived as a non-uniform pyramidal roof with 4 different slope angles, but when looked at from below, a pattern of parallel lines magically appears, thus fulfilling our client’s desire to create a sleek and visually acceptable design. The steel girders of the skylight (hot finished rectangular hollow sections, all aligned with each respective roof surface) are used to further support the roof, which consists of an aluminum structure and glass panels. Because of the 4 different slope angles of each roof surface, the bottom edge beam is a welded hollow section, allowing for inner stiffeners to be provided where needed. The connection details were conceived in such a way that the maximum amount of light can shine into the building. For this project, SCIA Engineer’s load panel tool was used, allowing for the automatic division of uniformly distributed surface loads over the girders that are designated to a certain surface panel. The project presented numerous challenges, resulting directly from the complex geometry yet we have managed to achieve a beautiful structure which summarizes the art of engineering.
