Damage Detection In Metamorphic Stone Blocks Utilizing Impact-Echo Testing And Modal Analysis, Alexander C. Jording

Durham School of Architectural Engineering and Construction: Dissertations, Thesis, and Student Research

Existing buildings decay with the passage of time, and as a result, continually require maintenance or rehabilitation. When considering existing structures, testing is often necessary to complete structural analysis in preparation for rehabilitation or repair. Non-destructive testing provides a structural assessment method applicable to a variety of materials and structures. The hypothesis of this research is that impact-echo testing, one of the many NDT techniques, can be adopted to develop a reliable and standardized method to assess the condition of rectangular metamorphic stones. After the baseline material parameters and general response to impact-echo testing were established, a novel method to …
