DYNAMIC PROPERTIES OF THE PEDESTRIAN BRIDGE AT THE FACULTY OF CIVIL ENGINEERING OSIJEK

U diplomskom radu analiziran je dinamički odziv pješačkog mosta na Građevinskom fakultetu Osijek uslijed različitih opterećenja pješaka. Za ukupnu ocjenu ponašanja pješačkog mosta provedena je eksperimentalna i numerička analiza pomoću računalnog programa. Dinamičko ispitivanje provedeno je u više faza ovisno o promatranom opterećenju. U prvoj fazi analizirana su ambijentalna ispitivanja, a u ostalim fazama, promatrano je ponašanje konstrukcije pješačkog mosta uslijed hodanja i skakanja pješaka. Dobivenim rezultatima dinamičkim ispitivanjem kalibriran je model pješačkog mosta koji najviše odgovara ponašanju realne konstrukcije. Model je izrađen u programskom paketu SAP 2000 v.18 te su modelirana opterećenja jednaka opterećenjima pri dinamičkom ispitivanju. Analizom i usporedbom rezultata eksperimentalne i numeričke metode opisan je dinamički odziv pješačkog mosta.In this work, the dynamic behavior of the pedestrian bridge at the Faculty of Civili Engeneering in Osijek was analized. Experimental and numerical analysis using a computer program were performed for the overall assessment of pedestrian bridge behavior. The dynamic test was performed in several phases depending on the applied load. In the first stage, the ambient vibration tests were analyzed, and in other phases, the behavior of the pedestrian bridge construction as a result of pedestrian walking and jumping was determined. The results obtained by dynamic testing were used for calibration of the model in order to produce the real constructive behavior. The model was created in the SAP 2000 v.18 program package and the modeled were similar to the loads used in dynamic testing. By analyzing and comparing the results of experimental and numerical methods, the dynamic response of the pedestrian bridge is determined
