Static and dynamic response of damaged prestressed RC beams flexural strengthened with CFRP
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.
