Secondary title:	Analysis of viaduct Ravbarkomanda according to standard EC 8/2
Secondary abstract:	The graduation thesis deals with the seismic analysis of the viaduct Ravbarkomanda according to the standard Eurocode 8/2. The seismic load was defined according to the standard Eurocode 8/1. Modal analysis with the design acceleration spectrum was used in the study. Different types of the seismic response were examined, using different reduction (behavior) factor of the seismic load. The seismic demand was compared with the strength of the columns, assuming that the strength would be ensured in spite of deficient construction details. Based on the same assumption, the ductility of columns was estimated, too. Displacements of the structure and the seismic demand in the elastomeric bearings (above the columns) were also analyzed. The analysis of the structure, supported by the strengthen columns (using concrete jackets), was also made. The increase of the stiffness and related increase of the seismic load were particularly investigated. It was found that the flexural strength of the columns could resist the seismic demand, which is related to the limited ductile response. When comparing the strength and demand, it was assumed that the construction details could ensure such flexural strength. This was proved by the experiment that was done at the ZAG. The shear strength of the short columns, defined according to EC8/2 was found insufficient. Assuming that the construction details were adequate, the ductility of columns was found suitable. The collapse of the elastomeric bearings above the short columns was found possible. It was found that the seismic demand in the structure supported by jacketed (strengthen) columns could increase up to 35%.
