Behaviour of a Single-storey Models With Different Connections Between Walls and Slab Subject to Seismic Base Excitation

U ovom radu je cilj bio prikazati ponašanje jednokatnih modela konstrukcija s različitim vezama između zida i ploče uslijed djelovanja horizontalnih potresnih pobuda. U radu je izvedeno analitičko te numeričko rješenje jednadžbe kretanja za slobodne prigušene oscilacije te prisilne prigušene oscilacije. U eksperimentalnom dijelu rada je provedeno sedam ispitivanja fizikalnih modela jednokatnih okvirnih konstrukcija sa krutom i zglobnom vezom između zidova i ploče pričvršćenih na potresnu platformu. U prva tri su okviri bili podvrgnuti harmonijskim pobudama podloge, a za ostala četiri ispitivanja su korištene vrijednosti stvarnih potresa, skaliranih na mogućnosti potresnog stola. Na temelju usporedbe eksperimentalno uočenog ponašanja dva različita okvira doneseni su zaključci o utjecaju karakteristika, posebice krutosti i prigušenja, na dinamički odaziv okvira.The main goal of this work was to show the behavior of single-storey models with different connections betwen the walls and the slab subject to a horizontal seismic excitation. The thesis presents an analytical and numerical solution of the equation of motion for free damped oscillations and forced damped oscillations. In the experimental part of the work seven tests are carried out with fisical models of single-storey frames with rigid and hinged connection betwen the walls and the slab attached to a seismic platform. Harmonic base excitations were used for the first three, while in the other four tests the models were subject to values of actual earthquakes, scaled to the capabilities of the earthquake table. Couclusions about the effect of the characreristic, specifically stifness and damping, on the dynamic response of the frame are carried out, based on the comparison betwen the experimentaly observed behaviours of the frames
