Sažetak
The paper summarizes earthquake calculation in accordance with Eurocode 8, ACI regulations and codes applied in Croatia (Europe). Basic data about earthquake is given. Overview of seismic devices is presented. Calculations for Zeceve Drage (Croatia) bridge are made. Time history analysis was calculated for accelograms based on earthquakes occurring in Petrovac (1979), with magnitude of 6.8, and in Ulcinj (1979), with magnitude 5.3, (former Yugoslavia). New methods of structure protection with dampers were applied on the bridge. Spectrum analysis based on EC8/2 for ground acceleration of 0.19g for the past period of 500 years, and time history analysis for ground acceleration of 0.25g and for the past period of 1000 years was used. The damper effect on a bridge with two spans was tested in a laboratory of Civil Engineering Faculty of Zagreb University, Croatia.
