https://doi.org/10.4467/2353737XCT.14.079.1856The article presents the results of tests, aimed for determining the influence of the acoustic wave, generated in the performance and sport hall, on the changes of forces in the tendons elements of the roof. The measurements have been realized in the existing object, build in the sixties of the 20th century, by simulating the actual acoustic influence with use of loudspeaker system at various sound intensity levels and wave lengths.

https://doi.org/10.4467/2353737XCT.14.377.3688Structures located in areas affected by mining operation are subjected to movements and tilting. Continuous monitoring of the structure’s response to these forces allows for the control of their impact on the technical condition of the structure. In the case of railway structures, the measurements may allow further determination of the impact of modifications to the geometry of the structure on the track. This paper presents the results of observing indications of Structural Health Monitoring installed on an actual bridge construction under which mining operations were being conducted.
