Abstract
This article is aimed at the analysis of the behavior of a fiber-reinforced concrete slab in contact with subsoil during dynamic loading in close proximity. The properties of such slabs are important for evaluating their dynamic response, though the properties of the subsoil environment through which the vibrations propagate must also be taken into account. The analysis itself was performed on the basis of the results obtained from experimental measurements during seismic excitation with a calibrated impact. There were three concrete slabs tested, with varying amounts of fiber. The standard Vistec seismic instrumentation was used for measuring the dynamic response. The results of the experiment were processed in both the amplitude and frequency domains, and a graphic comparison in the waveform and frequency fields was made. The results acquired from this experimental research may support a more objective approach during the evaluation of dynamic impacts ranging from anthropogenic impacts to building structures.
Highlights
Anthropogenic vibrations are generated in the surroundings of roads as well as train and tram lines [1,2,3]
It is the frontal distribution of the maximum amplitudes of the oscillation velocity which significantly attenuate with increasing distance from the source of dynamic load
This article presents an experimental study of the distribution of vibrations over the surface of a concrete slab reinforced with steel fibers
Summary
Anthropogenic vibrations are generated in the surroundings of roads as well as train and tram lines [1,2,3]. Even vibrations that do not reach the limit values in the structures or do not exceed hygienic standards can have a very negative effect on, for example, sensitive devices or technology within the structure. Monitoring and limiting these vibrations can help to achieve the sustainable development of cities and the life within them
