Dynamic Response to Base Excitation of a Single-storey Model With Rigid and Hinged Joint Between the Wall and the Slab

Ovaj završni rad obrađuje razliku dinamičkih odgovora dvaju okvira, jednog sa 4 kruta spoja, a drugog sa 3 kruta i jednim zglobnim spojem. U uvodu je objašnjeno kako promatramo potres u mehaničkom smislu riječi, te su definirana fizikalna svojstva dvaju okvira koje analiziramo. Izvedena je jednadžba kretanja pomoću koje je izračunat koeficijent prigušenja svakog okvira. Radi potvrde proračuna, proveden je eksperiment slobodnih oscilacija na svakom okviru, gdje su pomaci mjereni optičkim mjernim sustavom. Zaključno su okviri podvrgnuti djelovanju četiri različita potresna zapisa pomoću potresnog stola, te su analizirani njihovi relativni pomaci.In this undergraduate the difference in dynamic response between two frames is examined - one with four rigid joints and the other with three rigid joints and one hinged joint. The mechanical explanation of seismic activity and a definition of the physical characteristics of the two frames under examination are given in the introduction. The equation of motion was derived and damping coefficinet calculated for each frame. A free vibration experiment is conducted on each frame to verify the calculations, where the displacements were measured by an optical measurement system. Finally, the frames' relative displacements when subjected to the influence of four different seismic records using a seismic table are examined
