Design for earthquake resistance of structures is described in Eurocode 8. Monitoring of natural or technical (artificial and triggered) vibrations is a standard requirement for management of construction sites. Vibrations vary in periodicity, duration, time and location of occurrence etc. The intensity of vibrations depends on many parameters, first of all local geology, subsurface layers, type of source, prevailing source frequency, parameters of influenced structure ... Significant diversity of sources influencing the intensity of a seismic event on the surface, is the reason why sufficiently credible results cannot be obtained and simple relations cannot be derived without a substantial number of seismic measurements. The acquired waveforms need to be interpreted both in amplitude and frequency domains. General assessments of the impact of vibrations on structures are based on international standards for vibration assessment. Many countries also specify maximum
permissible values in their national standards.
