Structural Health Monitoring of a Historic Church: Theory and Practice of Diagnostic Approaches Used to Control Risks and Costs

Abstract

Structural Health Monitoring is an exciting opportunity to use real time quantitative data of a structure’s response in analysis and evaluation. However, this technology has yet to achieve common use in practice and remains linked to research of iconic buildings. This paper discusses the challenges and opportunities for use of SHM for widespread projects with damaged buildings and limited budgets. The SHM approach used was long term low frequency (static) data collection of both environmental inputs and structural responses. This data was used to develop relationships between loads and responses that could be effectively used to determine safety of the building and where in the structure deterioration continues.
