ABSTRACT
This article presents a new approach to monitor structural behavior of large historical timber structures. During the assessment of the method, data was collected at the research station located in the attic of the historical roof structure of a medieval church. The collected data was analyzed in terms of the influence of environmental actions (such as temperate change and wind load) and the results are presented in this article. This project is significant because the measurements of deflections of a very large structure are taken in situ. The article explains the complexity of such measurements as well as provides an overview of selected methods of measurement of structure deformations. A new application of draw-wire sensors as measurement instrument is presented with the results confirming the applicability of such sensors for deflection measurements
Key words: structural health monitoring, draw-wire sensor, environmental actions, timber structure, large structure.
