GB/T 14124-2009

This standard specifies the basic principles for measuring and processing data necessary to evaluate the impact of vibration on buildings. Here, we are not concerned with the vibration source itself, but rather with its dynamic range, frequency, or other parameters. The evaluation of the impact of structural vibration primarily focuses on the response of the structure, and includes appropriate analysis methods to determine frequency, duration, and amplitude. This standard only applies to the measurement of structural vibration and does not consider sound pressure or other forms of pressure waves, but it does require considering the response to these excitations. Here, a building is defined as a structure on the ground that is inhabited. Certain specific structures such as columns, chimneys, derricks, and structures are not considered, although they are often frequented by workers. The structural response of a building is related to the excitation source. The ultimate purpose of establishing this standard is to test the measurement methods under the action of the vibration source (i.e., the frequency, duration, and amplitude of the excitation). The excitation sources of concern include earthquakes, explosions, wind pressure, acoustic shocks, internal machinery, traffic, and construction work. Note: Artificial excitation is very different from earthquakes. Earthquakes are more violent and last for a long time, and their effects on structures are much more profound. Earthquakes can cause damage over long distances, release much greater energy, and generate different forms of waves. Therefore, the same parameter values (such as the peak velocity of particles) have different impacts on buildings.
