Sažetak
This paper presents experimental results of static and dynamic response of damaged RC beams strengthened with CFRP strips and sheets. Three prestressed RC beams with T cross section were tested. Beams were subjected to monotonic loading with increasing load steps with four-point bending setup in order to generate different damage levels in specimens. CFRP strengthening was applied on the specimens after they were damaged by loading to 50% of their flexural capacity. Modal tests were carried out after each loading-unloading cycle. Beams were excited by the impact hammer. Frequency response functions were processed using Dewesoft software to obtain natural frequencies, and corresponding damping ratios and mode shapes.
