In the North West of Tehran, one of the largest business centres in the Middle East, the Iran Mall, is actually built. It consists of areas for business, sports and cultural activities, and of a large hotel complex. This hotel is dominated by a huge glazing façade rising on the north and the south side almost 100 m up and connecting both lateral façades with a long glazing roof. The glass panes are attached to hybrid system, consisting of horizontal steel frames and prestressed vertical tension rod systems. The roof area consists of Vierendeel frames and circular tubes, with prestressed tension rods in‐between, to support the glazing. This paper is about the central glazing element, the Glass Bow. It describes the design process, analysis and detail design, as well as fabrication, logistics and installation. Parameter studies have been carried out to develop the tension system. Seismic interaction with the main building was taken into account. Glass and supporting structure have been developed to comply with local regulations, and local climatic condition.
