Estimation of Peak Relative Velocity and Peak Absolute Acceleration of Linear SDOF Systems

In seismic analysis and design of structures, true velocity and absolute acceleration are usually approximated by their corresponding pseudo-values. This approach is simple and works well for structures with small damping (less than 15%). When the damping of a structure is enhanced for response reduction, it may result in large analysis and design errors. Based on the theory of random vibration and the established mechanism of seismic response spectra analysis, a method is developed: 1) to predict the relative velocity spectra with any damping ratio level directly from the 5% standard pseudo-acceleration spectrum; and 2) to estimate the peak absolute acceleration. The accuracy of both is validated by using 2 selected ensembles of ground motion records.
