Dynamic analysis of a historical monument: retrofit using shape memory alloy wires

다국어 초록 (Multilingual Abstract)

The effectiveness of using the advanced seismic protection technology based on shape memoryalloy (SMA) dampers to preserve a historical minaret is investigated. The proposed studied case, the minaretof Mansourah, is a seven century old minaret located in Tlemcen, Algeria. Its original height was of 47m,while nowadays, the monument is half destructed and its current height reaches the 40m. The proposedseismic retrofit is based on the technique that utilizes SMA wires as dampers for the upper flexible part ofthe minaret. The effectiveness of the proposed technique is numerically evaluated via non-linear finiteelement analysis using the structural software ANSYS. The effectiveness of the proposed device inmitigating the seismic hazard is demonstrated by the effective reduction in its dynamic response.
