Abstract
The paper presents results of an analysis conducted in order to determine a cause of an emergency state of a timber roof rafter framing of a central nave ceiling in a church. The article showed an assessment of the current technical conditions, a description of the diagnostic tests performed and the results of the static strength analysis. Based on that information, the causes of this emergency state are described as the consequence of contractor’s errors during the execution and significant derogations from the construction design. Moreover, an implementation of a repair programme in order to restore the full value in use of the building is recommended.
Highlights
Religious buildings are classified as public buildings
The emergency state of the structure was a consequence of a change of the original static diagram, a change of the intermediate purlin’s material, a lack of due diligence of the roof construction execution and the negligence of experts performing an inspection of the technical condition
The data that was collected during the on-site verification of the timber roof construction of the central nave allowed building a 3D model of the roof and performing a static strength analysis
Summary
As experience shows, religious buildings are often subjected to construction breakdowns or failures [1,2,3]. Given their function and useful life, such facilities should be characterized by greater durability and load bearing. The executed support was not overly interfering with the construction system and it allowed a continuing use of the building. The results of examinations and analyses enabled determining the factors that caused the emergency state They allowed formulating recommendations that concerned an implementation of a repair programme in order to restore the full value in use of the building
