Sažetak: This article shows the strain analysis on two cantilever cast-in-place prestressedconcrete bridges during construction. Strain gauges, measuring strain based onthe change in electrical resistance, were installed on both structures in order toobtain strain results during and after construction. Nonlinear numerical modelswere made to simulate the realistic behaviour of the structure and show theeffect of creep and shrinkage during the construction phases. The numericalmodel taking into account creep and shrinkage is validated and shows goodoverlap with the measured results. Relative compressive stresses as well as thenecessary precamber are shown. The effects of creep and shrinkage areanalysed. Finally, the data can be used to analyse and compare other similarbridges and validate different numerical models. A recommendation for thedesign of future prestressed concrete balanced cantilever bridges is given.
