Sažetak
The analysis of Maslenica concrete bridge monitoring has been carried out. The bridge was finished in 1997. The main girders of the superstructure and the arch were analysed during different construction phases. It appears that there was a considerable shrinkage of concrete in girders after their pouring because of a relatively small moisture level at summer time when the measurements were undertaken. This caused compression in the reinforcement. The stiffness of girders was determined by means of the modulus of elasticity, by measuring their natural frequencies, and by means of concrete compression strength. By measuring stresses and displacements during construction and by comparing it with the values obtained by means of NELIN program which includes the material and geometrical non-linearity, a solid qualitative correspondance between theoretical and experimental research results has been established.
