The Application of SMA Dampers in Passive Control of Ancient Tower Structures

Abstract eng:
The majorities of Chinese present ancient pagodas all mix together the highlighted arts of foreign cultures and traditional architectures of China, and are typical masterpieces of ancient buildings. The ancient pagoda protecting research is a major task of cultural relic protection. In this paper the historical changes and engineering situations have be fully investigated and the material constituents, detailing types, existing inclination and cracks etc. are studied. Then, the mechanical properties of SMA wire are tested, and a desirable SMA damper is designed. The shaking table test had been executed on the ancient pagoda model structure with and without SMA dampers. Experimental results show that the model structures with SMA dampers can improve its earthquake resistance capacity so that the concluding remarks could not only provide a theoretical foundational and technical support, but provide references for protection and repair of other historical buildings.
