000011445 520__ $$2eng$$aDue to the crash of the computer driving the ENEA shake-table, only paper sheets and images documented the results obtained for the first of two masonry specimens tested. Raster images were digitized by means of a special purpose algorithm and digital data showed the need to be processed so as to improve time origin sinchronization and measurements coherence. The test results for the second masonry specimen were instead recorded on a computer and a backup copy of all files (input and recording from all channels – accelerometers and LVDT) was immediately made. Unfortunately, the input record was not aligned (same time origin) with the other channels. To solve this problem all time-histories were processed and time-shifted so as to maximize the cross-correlation function and the measured coherence.
