A method for simulating and representing strong ground motion

Jurkevics, Andrejs January 1978 (has links)
A method for representing and synthesizing strong motion accelerograms is proposed in this thesis. The procedure models an acceleration time-history as a non-stationary second order autoregressive (AR) process. Three AR parameters are determined from the data in a time-adaptive manner. They provide a quantitative description of the time-varying spectral content of the recording. The AB parameters may also be utilized as prediction filter coefficients, enabling one to generate a suite of artificial accelerograms, each having the same time-dependent spectral content as the target record. The simulated time-histories may be used for computing structural response in earthquake-prone areas. This analysis has been extended to include a number of recordings obtained during earthquakes of various magnitudes (M) at a variety of epicentral distances (D). As a result, 'type curves' representing the empirical behaviour of the three AB parameters have been determined. Although incomplete, this information may be used to generate artificial accelerograms for arbitrary combinations of M and D. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

A visualization of an experiment on a shake table

Penn, Michael January 1991 (has links)
A model to enable a graphics presentation of an experiment has been developed. The model was developed specifically for experiments run on a shake table for earthquake simulating tests but could be used for any experiment that involves movement and instrumentation. By integrating the results obtained from the instruments used during an experiment it is possible to display, on a computer screen, the motion of the model being tested. By use of visualization techniques it is possible to obtain a graphical representation of all the instruments being used and thereby producing a picture of the entire experiment. / Science, Faculty of / Computer Science, Department of / Graduate
