Abstract

U ovom radu opisan je postupak ispitivanja mosta na autocesti probnim opterećenjem. Ispitivanje probnim opterećenjem je vrlo često obavezna radnja prije puštanja mostova u promet i može se podijeliti na statičko i dinamičko. Statičko ispitivanje temelji se na mjerenju pomaka mosta uzrokovanih probnim opterećenjem. Dinamičko ispitivanje temelji se na određivanju dinamičkih karakteristika mosta i mjerenju odgovora mosta na dinamičko opterećenje u realnim uvjetima upotrebe. Tema rada je obrađena po sljedećim poglavljima: Prvo poglavlje opisuje regulativu vezanu uz ispitivanje mostova probnim opterećenjem,drugo poglavlje sadrži tehnički opis konstrukcije predmetnog mosta, treće poglavlje opisuje program ispitivanja, četvrto poglavlje obrađuje rezultate ispitivanja,peto poglavlje obrađuje numeričku analizu mosta i u šestom poglavlju dana usporedba numeričkih i eksperimentalnih rezultata s konačnim zaključkom o sveukupnom ponašanju konstrukcije mosta.

Abstract (english)

This thesis describes the procedure load test of a motorway bridge. Load testing is very often a mandatory procedure before bridges area released to traffic and it can be divided into static and dynamic testing. Static load test is based on the measurement of bridge displacement caused by the test load. Dynamic load test is based on determination od the bridge dynamic parameters and measurement of the bride response to the dynamic load in real conditions of use. The topic of the thesis is covered by the following chapters: the first chapter describes of the structure, geometric characteristics and material of which the bridge is built, the second chapter describes the regulations covering the testing of bridges with test load, the third chapter describes the test program, the fourth chapter deals with the test results, the fifth chapter deals with the numerical analysis of the bridge, the sixth chapter compares the numerical and experimental results and gives the final conclusion on the overall behavior of the bridge structure.
