m•connect stainless steel systems save the 2700 years old Yeha temple
The Yeha temple is one of the oldest building in Ethiopia and the highest remaining religious building of the first millennium BC in East Africa. The 2700 years old building was in acute danger of collapsing. In the upper part of the antique building the complete inner shell of the two parts brick wall is missing. The still existing old outer shell is up to 14 m high and has inner and outer warpings. Over the centuries the building structure becomes weak. The temple were checked with a comprehensive examination and documentation of the building. All architectural and technical surveys were done with a terrestrical laser scanner. To ensure an adequate stability of the upper stoneworks the monument committee of DAI and the Ethiopian authorities decided to rectorate the objective to preserve […]the historical character. A stainless steel frame supports the fragile building structures and is connected on over 200 points with the walls. With the help of the scan data the support construction frame could be installed millimeter-precise. The filigree elements of the m•connect tension and compression strut systems were used for the vertical bracings and rear tensionings. The stainless steel systems M16, M20 and M30 were selected for this installation. This spectacular project of cultural preservation in this region based on the successful cooperation between Ethiopia and Germany and should be a good example to maintain historical heritage worldwide.
