Original Abstract
In the field of vibroacoustic testing methods an experimental modal analysis is vastly used, which allows inspecting natural frequencies and damping ratios of test specimens. In the literature a numerous approach is being used for laboratory testing setups which mostly consist of an elastic suspension of test specimen and usage of different types of accelerometers, shakers, and modal hammers. The presented paper focuses on the comparison of different test setups of used sensors and impact exciting of a test specimen of slab made of alkali-activated slag mortar, which was degraded by ultraviolet light. The paper aims to find optimal setup combination for testing of such material by experimental modal analysis and decide if ultraviolet light alter the vibroacoustic properties of test specimens.
