The on-site earthquake early warning system is under development for the area near the earthquake epicenter to provide information such as earthquake magnitude, the arrival time and the intensity of the strong shaking for free field as well as the structural response, etc. The real-time strong motion signals recorded from Taiwan Strong Motion Instrumentation Program (TSMIP) were used to train n...

The harmonic wavelet transform is employed to analyze various kinds of nonstationary signals common in aseismic design. The effectiveness of the harmonic wavelets for capturing the temporal evolution of the frequency content of strong ground motions is demonstrated. In this regard, a detailed study of important earthquake accelerograms is undertaken and smooth joint time-frequency spectra are p...

Numerical analysis applied to the Beznar dam accelerograms (longitudinal and transversal components) shows that the Fourier amplítude spectrum is a good approxímatíon to the pseudo-velocíty spectra. Thís fact makes possible to use displacement ar velocíty seismograrns to generate acceleration of the ground in places where acceleration data are not avallable. Maximae accelerations determined nea...

Through the last three decades different seismological and engineering approaches for the generation of artificial earthquakes have been proposed. Selection of an appropriate method for the generation of applicable artificial earthquake accelerograms (AEAs) has been a challenging subject in the time history analysis of the structures in the case of the absence of sufficient recorded accelerogra...
