tom nr IV/4

1755--1769

The article presents a methodology of technical condition assessment of masonry and timber structures of historical buildings, demonstrated on the example of palace complex at Gorzanów. Based on a comprehensive diagnostic study prepared by the authors, both on location and in the laboratory, a flowchart was developed to illustrate technical condition assessment procedures for historical buildings as well as for determining existing damage. The flowchart presented here may be found helpful by those providing expert opinions while designing their research and determining damage causes and investors who undertake such a difficult task as an adaptation of historical buildings to modern functional requirements.

Diagnostics of existing buildings includes, among others research to assess their durability. In the case of reinforced concrete structures, such tests include semi-destructive electrochemical tests to forecast the corrosion risk of steel bars in concrete, and one of the methods used is the electrochemical, polarizing galvanostatic pulse method. The aim of the article was to recognize the influence of element effort on the measurement results obtained with this method. For the tests, a reinforced concrete cantilever slab loaded monotonically was used. During the tests, the stationary potential and corrosion current density of the main reinforcement bars, as well as the resistivity of the concrete cover, were measured. Based on the results obtained, it was found that the level of effort on the element affects the values of the measurements performed. Differences in the values of measured parameters at different levels of element effort are sometimes so large that they may significantly affect the conclusions about the corrosion risk of the tested reinforcement, and thus incorrectly estimate the durability of the tested element.

The paper describes the case of monitoring the technical condition of a historic sacral building after a failure and during renovation works. In order to monitor the condition of the building, safely conduct diagnostic work, identify the causes of failures and safely carry out renovation works, a detailed Facility Monitoring Program has been developed, which has been implemented, is operational and is a source of valuable data used to assess the current condition of the facility.
