Influence of the Change in Mass and Width of a Single-storey Model on its Dynamic Response to Base Excitation

Ovim završnim radom cilj je bio usporediti utjecaj promjene mase i širine ploče jednokatnog modela na dinamički odgovor na pobudu podloge. Izvedena je jednadžba kretanja i provedeno eksperimentalno ispitivanje problema. Ukupno je provedeno pet laboratorijskih ispitivanja za dva različita umanjena jednokatna okvira koji su se nalazili na platformi potresnog stola. Najprije su laboratorijski ispitane slobodne oscilacije oba okvira zato što su iz njega određene njihove dinamičke karakteristike. Sljedeća četiri ispitivanja provodila su se za okvire pobuđene potresnim zapisima koji su se događali u prošlosti. Rezultati ispitivanja dobiveni optičkim mjernim metodama su analizirani te uspoređeni s analitičkim predikcijama.The objective of this final paper was to compare the influence of the change in mass and width of the single-story top panel on the dynamic response to base excitation. The equation of motion was derived and an experimental testing of the problem was carried out. In total, five laboratory tests were conducted for two different small-scale single-story frames located on the platform of the shaking table. First laboratory examination of free oscillations of both frames were carried out and their dynamic characteristics were determined from it. The next four experiments were conducted for frames subjected to earthquake records from earthquakes that occurred in the past. The test results ob- tained by optical measurement methods were analyzed and compared with analytical predictions
