In order to preserve historic structures, it is necessary to understand their structural design and performance and preserve both as our technical heritage. Only this will provide a solid basis for any structural intervention, if it is needed at all. Such interventions may require modern key technologies, considering that often enough, such structures are not complete anymore or the ancient builders did not consider certain loads properly, especially earthquakes. Modern key building technologies may not harmonize with ancient ones. Applying them can lead to destruction rather than preservation, as we are now painfully aware. There is no magic potion that ensures this harmony, but for seismic protection of masonry and stone block structures, the Tendon System has a lot of promise. This is demonstrated in applications and research involving the 18th c. AD Collegiata di San Michele in Solofra, Italy, the 12th c. AD bell tower San Giorgio in Trignano, Italy, the 13th c. AD Madrassa in Erzurum, Turkey and the 5th c. BC Temple of Neptune in Paestum, Italy.
* Prof. Dr., Universität Kassel, Germany
Born in 1956, he has master degrees in civil engineering from Ruhr-Universität Bochum, Germany and University of Washington, Seattle, USA. After his doctorate from Ruhr-Universität Bochum in 1988, he obtained post-doc fellowships to research structural control systems for earthquake protection and advanced seismic testing methods at University of Washington, USA, Building Research Inst., Tsukuba, Japan and Universität Innsbruck, Austria. Returning to Germany, he became the head of the structural laboratory at Universität Kaiserslautern. In 1998, he was appointed full professor at Universität Rostock, Germany, and in 2002, he assumed his current position as professor for steel- and composite structures at Universität Kassel, Germany. In 2007, he founded the German Humboldt Alumni Association serving as its president for 10 years. His research is internationally recognized in seismic protection of buildings and bridges using advanced structural systems (seismic control); The simulation of steel-concrete composite structures; Online coupling of numerical models with specimen (hybrid simulation) and ancient building technology.
