چکیده
Jerk, or jolt, is the time derivative of acceleration. Jerk response of inelastic Single-Degree-of-Freedom (SDOF) systems to pulse-like earthquakes is examined in the current study. Compared with usual non-pulse-like motions, pulse-like near-fault ground motions can impose significantly higher demands on structures. This study presents constant-strength spectra based on the jerk response of inelastic SDOF systems under the 91 pulse-like earthquakes. To model these effects, constant-strength spectra are developed based on the jerk response, considering variations in structural characteristics, such as the strength factor, hysteretic behavior, and viscous damping ratio. The results show, the viscous damping ratio is slightly higher in the short normalized period region than the long normalized period region. Moreover, an analytical equation is proposed to estimate the demand of jerk in inelastic SDOF systems as a function of elastic vibration period over the pulse period and the strength reduction factor, for different hysteretic models and damping ratios.
