Abstract

U radu se elaborira ponašanje konstrukcije cestovnog mosta uslijed djelovanja probnog opterećenja. Cilj ove vrste ispitivanja je utvrditi ponaša li se konstrukcija u skladu s odredbama projekta. Općenito, prema vrsti opterećenja ispitivanje se može podijeliti na statičko i dinamičko probno opterećenje. Statičko probno opterećenje podrazumijeva postavljanje tereta na mjestima predviđenim programom ispitivanja, a uobičajeno je popraćeno mjerenjem pomaka i relativnih deformacija na konstrukciji. Prilikom dinamičkog probnog opterećenja uobičajeno se određuju dinamički koeficijenti i osnovni dinamički parametri konstrukcije mosta. Zaključno, eksperimentalno dobiveni rezultati uspoređuju se s teorijskim vrijednostima. U radu je općenito obrađena tematika ispitivanja mostova probnim opterećenjem i opisana je relevantna regulativa. U sklopu izrade diplomskog rada provedeno je ispitivanje cestovnog mosta probnim opterećenjem, te rad sadrži sve podatke o predmetnoj konstrukciji te prikaz i analizu svih podataka dobivenih pri ispitivanju kao i usporedbu rezultata ispitivanja sa rezultatima dobivenim iz numeričkog modela mosta.

Abstract (english)

This thesis elaborates the behaviour of a road bridge structure subjected to a test load. The purpose of this type of test is to determine whether performance of the structure matches the predictions of the design. Generally, this test can be a static test or a dynamic test, depending on the type of load. In a static load test, the structure is loaded with a dead load according to the test programme and the displacements and strains of the structure are measured. In the dynamic load test, the dynamic coefficients and the basic dynamic parameters of the bridge structure are determined. Finally, the experimentally obtained results are compared with the theoretical values. This thesis includes a general description of the load testing of bridges and the corresponding regulations. Within the scope of the thesis, a load test was carried out on a road bridge. The thesis therefore includes all the technical data of the bridge in question, all the test data obtained as well as their analysis and comparison of the test results with the results of the numerical model of the bridge.
