Examples in Context
- It is recommended that the peak ground velocity ( PGV ) and ground energy density ( E () are the parameters that can be used to estimate the damage degree of structures in the near-field environment.
- Under the premise of fitting the target acceleration response spectrum, the peak ground velocity is obtained by a separate adjustment of long period component of the ground motion Fourier Spectrum.
- The E_H / E_I ratio for the mass-proportional damping model is the biggest one, with the increase of peak ground velocity to acceleration ratio ( V / A ), the E_H / E_I ratio for the Rayleigh and stiffness-proportional damping model will be close to mass-proportional damping model.
- When the scene on the ground is photographed from an aircraft, the velocity in the velocity - height ratio for the image-moving compensation is one of the ground relative to the aircraft, i. e. so called ground velocity.
- The outcomes indicate that under the effect of velocity pulse the increment of PGD ( peak ground displacement ) is greater than that of PGV ( peak ground velocity ), which has less influence on PGA ( peak ground acceleration ).
