Abstract

European codes and recommendations have been reviewed with respect to critical vibration levels, causing damage to buildings. It was found that the variation of the vibration threshold levels was large between the different codes. A rational approach to assess the damage caused by ground vibrations is proposed, based on wave propagation theory. The wave length appears to be the most important parameter. The damage potential was found to be greatest when the length of the propagating wave is equal to or shorter than the length of the building. The wave length can be determined from the frequency and wave propagation velocity. The critical dynamic ground distortion has been back-calculated from the requirements in the different codes and from published recommendations. The critical vertical particle velocity, causing damage, can be calculated if the wave propagation velocity is known. Also other factors such as the source of the vibrations, the building conditions and the degree of damage have been considered. A comparison of the proposed relationship with existing vibration criteria shows surprisingly good agreement.

Damage Criteria for Small Amplitude Ground Vibrations

St. Louis, Missouri

European codes and recommendations have been reviewed with respect to critical vibration levels, causing damage to buildings. It was found that the variation of the vibration threshold levels was large between the different codes. A rational approach to assess the damage caused by ground vibrations is proposed, based on wave propagation theory. The wave length appears to be the most important parameter. The damage potential was found to be greatest when the length of the propagating wave is equal to or shorter than the length of the building. The wave length can be determined from the frequency and wave propagation velocity. The critical dynamic ground distortion has been back-calculated from the requirements in the different codes and from published recommendations. The critical vertical particle velocity, causing damage, can be calculated if the wave propagation velocity is known. Also other factors such as the source of the vibrations, the building conditions and the degree of damage have been considered. A comparison of the proposed relationship with existing vibration criteria shows surprisingly good agreement.
