![عکس صفحه اول مقاله: Using CFRP Lamellas for Strengthening of Dynamically Loaded Beams Using CFRP Lamellas for Strengthening of Dynamically Loaded Beams](/preview/png/859222.png)
The reinforced concrete (RC) beams strengthened with CFRP lamellas in bending areas were investigated in the frame of research activities of the Department of Structures and Bridges (University of Žilina). The research is focused on the existing bridge structures, which do not satisfy the traffic loads carrying capacity criterion. So, a bridge near village Kolárovice was observed. It is a six beams RC bridge structure with theoretical span 10.006 m, which do not satisfy the load-carrying capacity. Thus, it is needed to strengthen the bridge. The use of carbon fibre reinforced polymer (CFRP) materials (lamellas and sheets) is one of ways of strengthening of concrete bridges. Firstly, the strengthening is applied on the set of specimens of the T-beam in scale 1:3. The static and dynamic load is applied on the specimens. The dynamic load is representing the real traffic load on the bridge structure. The paper deals with the influence of the dynamic load on the load-carrying capacity of the RC beams subjected to bending.
