Abstract EN
Jerk is the time rate of acceleration and mainly represents the nonstationary component in high frequency band of the earthquake wave.
The study on jerk and its response spectra can enhance the recognition of the nonstationary ground motion.
The mechanical meaning and research value of jerk are described.
Jerk is recommended to be solved by establishing state-space equations and Runge-Kutta method.
The solution method of elastic and inelastic jerk response spectra under ground motion is established, and the accurate jerk spectrum should be calculated directly according to numerical computing instead of pseudo-acceleration spectrum.
The characteristics of jerk response spectra are studied according to the influencing factors, such as site condition, amplification factor, ductility factor, and reduction factor.
The concept of impact reduction factor is presented.
The statistical results show that the jerk spectrum has similar rules as the acceleration spectrum, and the amplitude is relative to the predominant period, especially for structures with short or medium period.
If the ductility is improved, the effective jerk will reduce obviously, and the impact reduction factor will be enhanced.
Different from the strength reduction factor, the impact reduction factor is nearly not relevant to the period.
