Abstract

U ovom radu opisani su postupci ispi􀆟vanja mostova probnim opterećenjem, kao i analiza
rezultata 􀆟h postupaka. Nadvožnjak koji se ispi􀆟vao i koji je odabran kao predmet rada je
nadvožnjak u okolici grada Siska. Ispi􀆟vanje mostova je postupak koji je propisan normom HRN
U.M1.046 (1984) te se provodi nakon izgradnje novog mosta, tj. prije puštanja mosta u
eksploataciju, ali se također provodi i za ocjenu stanja postojećih mostova. Prethodno
ispi􀆟vanju mosta potrebno je napravi􀆟 program ispi􀆟vanja unutar kojeg se pretpostavljaju faze
opterećenja na temelju izračuna efikasnos􀆟. Također programom se definira i oprema kojom
će se provodi􀆟 ispi􀆟vanje kao i mjerna mjesta gdje se provode mjerenja određenih
parametara. Na mostu se provodilo sta􀆟čko i dinamičko ispi􀆟vanje. U sklopu sta􀆟čkog
ispi􀆟vanja na predmetnom mostu mjerili su se ver􀆟kalni pomaci rasponske konstrukcije pod
utjecajem probnog opterećenja kamionima, a u sklopu dinamičkog ispi􀆟vanja određivani su
dinamički koeficijen􀆟 prilikom prolaska vozila te su određivani osnovni dinamički parametri
mosta. U radu je dan opis sta􀆟čkog sustava mosta, geometrije te ugrađenih materijala. Također
je dan i pregled regula􀆟ve vezane uz probna opterećenja mostova. Prikazani su rezulta􀆟
dobiveni ispi􀆟vanjem mosta, kao i rezulta􀆟 dobiveni na temelju numeričkog proračuna
konstrukcije kako bi se na kraju 􀆟 rezulta􀆟 međusobno usporedili. Na kraju je dan zaključak o
ponašanju konstrukcije na temelju već spomenu􀆟h rezultata.

Abstract (english)

This paper describes the procedures for the load tes􀆟ng of bridge, as well as the analysis of
the results of these procedures. The tested bridge chosen as the subject of the thesis is an
overpass located near the town of Sisak. The load tes􀆟ng of bridges is a procedure prescribed
by the HRN U.M1.046 (1984) standard which is conducted a􀅌er the construc􀆟on of a new
bridge, i.e., before the bridge is put into opera􀆟on. It is also carried out to assess the condi􀆟on
of exis􀆟ng bridges. Prior to bridge tes􀆟ng, a test programme must be developed, that defines
the load phases based on efficiency calcula􀆟ons. The programme also specifies the equipment
to be used for the test, as well as the measuring points at which certain parameters are
measured. The bridge was subjected to both a sta􀆟c and a dynamic test. In the sta􀆟c test
phase, the ver􀆟cal displacements of the span structure were measured under the influence of
test loads with trucks. In the dynamic test phase, the dynamic coefficients were determined
during the passage of vehicles, and the fundamental dynamic parameters of the bridge were
iden􀆟fied. The thesis also describes the structural system of the bridge, the geometry an the
materials used for its construc􀆟on. In addi􀆟on, the thesis provide an overview of the
regula􀆟ons rela􀆟ng to the load test of bridges. The results of the load test of the bridge are
presented together with the results of the numerical calcula􀆟ons of the structure, so that a
comparison of these results is possible. Finally, a conclusion is drawn regarding the behavior
of the structure based on these results.
