Abstract

Rad opisuje postupak ispitivanja mosta probnim opterećenjem. Ispitivanje mostova postupak je koji se provodi prije puštanja novoizgrađenog mosta u promet kao i za ocjenu postojećih mostova. Prema ranije izrađenom programu ispitivanja, na temelju kojega je definiran intenzitet opterećenja te faze ispitivanja, izvršeno je statičko i dinamičko ispitivanje. Statičko se ispitivanje temelji na mjerenju pomaka i relativnih deformacija od probnog opterećenja, a dinamičkim ispitivanjem se određuju vrijednosti dinamičkih koeficijenata te osnovni dinamički parametri konstrukcije. U radu je obrađena regulativa vezana za ispitivanje mostova, navedene su karakteristike analizirane konstrukcije mosta te oprema kojom se vršilo ispitivanje. Opisani su osnovni podaci o probnom opterećenju koje se koristilo prilikom izvođenja ispitivanja i obrađeni su rezultati ispitivanja. Izrađen je numerički model na temelju kojeg je napravljena usporedba rezultata eksperimentalne i numeričke analize te je dan zaključak o sveukupnom ponašanju konstrukcije.

Abstract (english)

This thesis describes the procedure of bridge load tests. Bridge testing is a procedure that is carried out both before commissioning of newly built bridges and for the evaluation of existing bridges. According to the previously established test programme, based on which the load intensity and test phases were determined, static and dynamic tests were carried out. The static load test is based on the measurement of the structural displacements and strains due to the applied test load and the dynamic load test is used to determine the values of the dynamic coefficients and the basic structural dynamic parameters. This thesis also describes the regulations for bridge load tests, as well as the characteristics of the tested bridge structure and the equipment used to perform the test. The most important data regarding the load used during the test are given and the test results are analysed. Finally, the results of the experimental and numerical analysis were compared based on the numerical model created for this purpose.
