heal.abstract	A 3500 old Minoan city that was covered with lava during the eruption of the volcano in Santorin was found almost intact after recent excavations. The archaeological site was covered over an area of 11800 m2 with a roof. The roof consisted of a space frame steel structure and had 13 spans with length ranging from 6,5 to 16,5 m. The structure was supported by tubular steel columns resting on bearings that acted as a seismic isolation. After completion of the works, part of the roof over an area of 500 m2 collapsed, causing a loss of one human life. In order to investigate the causes of the collapse, all important input data for design and construction were collected, which was followed by experimental and numerical investigations on the overall structure and its parts. The studies showed that the collapse was primarily due to overloading from the soil used to cover the roof, which was thicker and heavier than the specified one, and to a less extend due to indirect actions from erection processes and geometric imperfections in the form of deviation of bar lengths from the prescribed ones. Finally the brittle behaviour due to size and forms of the holes in the bars could not stop the collapse. © Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co. KG.	en
