vibration analysismeasurementcontrol

OVERVIEW FIELD OF APPLICATION: For construction works in cities and industrial areas, immission control with regard to the vibration caused is of considerable importance. The high building density has as a result that people in housing and office buildings are affected increasingly often by vibration events in their vicinity. Furthermore, for construction works, industrial production and blasting, the effects on existing buildings and structures must be investigated. This primarily involves the evaluation of the vibration with respect to the endangerment of buildings and structures. DESCRIPTION: This option allows the measurement and analysis of building vibration according to DIN 4150 for the purpose of the evaluation of its effects upon buildings and structures as well as people within them. Upon the occurrence of vibration, a marker is set in a vibrational velocity / frequency diagram at the position determined by the relevant frequency and the maximum velocity from the three axes. The guideline values for vibrational velocity in foundations of commercial buildings, housing and protected historical monuments are also shown graphically in the diagram. Thus, already during the course of the measurement the distribution of the markers shows whether and how often the threshold values for the relevant building type were exceeded. For evaluating the effects of vibration upon people in buildings, the option provides the takt-maximal value (maximum level in consecutive time intervals) of the frequency-weighted vibration signal, KB(t). The length of the time intervals is freely selectable.
