THE DYNAMIC-STATIC METHOD (DSM) FOR STRUCTURAL DISPLACEMENT ANALYSIS USING THE EXAMPLE OF A WOODEN CHURCH IN DOMACHOWO (POLAND)

Abstract. Medieval architecture in Poland is not widely represented in the tangible cultural heritage. A preserved structure with traces of medieval architecture is the parish church in Domachowo in southern Greater Poland (Wielkopolska). Due to numerous alterations and modernisations, it is now a complex structure showing clear signs of a damaged original geometry.

For this reason, a project was initiated to measure the stability of the structure, especially under the influence of extreme external factors: mainly gusts of wind and uneven sun illumination. The implementation of the project required using two methods of measurement: static, at fixed time intervals, and dynamic, recorded on an ongoing basis during the operation of variable loads. The outcomes consisting of a combination of both methods and the unconventional use of precise inclinometers for measuring wooden structures, opens up new possibilities for real-time analysis of structural deformations and ongoing monitoring of technical conditions.

The subject of this paper is to present the methodology of the conducted static-dynamic measurements (DSM) and the interpretation of their results, mainly in the context of assessing accuracy, stability of long-term readings with inertial sensors, and basic structural assessment.
