Vibration measurement in the degradation study of building construction materials

Brick objects are subject to large dynamic loads clearly reflected by generated vibration processes. The vibrations may affect the state of serviceability of structures by lowering the comfort of persons working there, as well as possibly reaching a level hazardous to the safety of the structures. The effect of vibrations on the structure is mainly manifested by additional stresses in a given cross-section, which are summed up with those resulting from static loads. The dynamic loads may cause damaging effects in buildings of various structural types or even lead to their destruction. The article describes a series of original analyses of the process of destruction of selected masonry objects using the experimental modal analysis. The research was conducted to improve the quality assessment of building structures in terms of the technical condition of masonry structures and meeting safety standards.
