Peak acceleration is the magnitude of the maximum seismic force on a building when an earthquake occurs. The greater the value, the greater the potential damage to the building. When the earthquake acceleration value is 2.5 ~ 8 cm/s 2, most people can feel that when it reaches 25 ~ 80 cm/s 2, the house shakes strongly.
Digital meaning
For example, China's new seismic intensity table (1980) stipulates that when the intensity is ⅶ, ⅷ and ⅹ, the corresponding average peak acceleration is 0. 125g, 0.25 g, 0.5 g and 1.0g respectively. The Japan Earthquake Intensity Table also includes the earthquake acceleration value corresponding to each intensity.
Design basic seismic acceleration value: the seismic acceleration design value exceeding probability 10% in the 50-year design reference period, including 7 degrees 0. 10g, 8 degrees 0.20g and 9 degrees 0.40g. ..
