Earthquake load
Setting | Description |
---|---|
Acceleration coefficient | According to AASHTO 3.10.4-1 it has different values depending on the Seismic Zones, maximum allowed value is 0.80. |
Damping | The use of 5% damping is considered as a reasonable representation of real structural behavior. |
Vertical Earthquake | If yes is selected the vertical ground motion during earthquake is applied. |
Factor | Vertical earthquake factor. |
The drawing shows the elastic seismic response coefficient normalized using the input ground acceleration A and the result plotted against the period of vibration. It is given for different soil profiles, based on 5 % damping.
