Sažetak
The investigation plans included the testing of the force magnitude in all the suspenders of the downstream and upstream bridge section, then the investigation of the force magnitude in main cables, and dynamic investigation of the bridge at excitation through live load and wind. The investigation of the force magnitude in suspenders was conducted using resonant dynamic method, and by measuring natural frequencies of suspenders' transversal oscillation. The force magnitude in the suspenders and main cables was determined on the basis of correlation between natural oscillation frequency and the stress. Results were given as comparison of forces for the years 2009 and 1993.
