Abstract:
The purpose of this work is to find the cause for glass panel failure of a high rise building in Dubai, UAE (United Arab Emirates). This kind of damage is common for skyscrapers with glass façade elements and presents a valid danger to pedestrians. Vienna consulting engineers (VCE) was commissioned to find out if the structural behaviour or the fixing of the glass is the cause of this failure. In order to do this VCE conducted a Structural Health Monitoring (SHM) campaign to assess the behaviour of the building and find out if the building movement can cause glass failure. Secondly the single structural member (glass element) was investigated to see if the failure has a local cause. As a result of this monitoring campaign, classic system identification has been made. Movements and structural behaviour has been measured and evaluated based on a finite element model of the structure. As expected, after such a short lifetime, the building is in very good condition. Nonetheless the movement of the building is greater than expected which can be a cause for glass failure. Furthermore the fixing of the glass elements is very stiff which can also result in glass failure. The evaluated causes are two of many possibilities which can lead to glass failure. As a conclusion a list of possible reasons for the investigated glass failure is given. The reaction of the building management was to build arcades and sun roofs to protect pedestrians and valuables from falling glass. Otherwise no measures have been taken.
