EFFECTIVENESS OF STRENGTHENING OF REINFORCED CONCRETE BEAMS WITH THE USE OF COMPOSITE MATERIALS

Wide spread of RC structures in construction projects indicates the necessity their service life prolongation. Perspective possibility to increase strength is use external composite tapes. The article presents theoretical research on effectiveness strengthening bended elements with Work also includes comparative analysis basis calculations, according normative regulations. With developed algorithm parameters stress-strain state and deformability beams, strengthened tapes were obtained. Study identified, that most critical parameter was steel bars` strain yield point. Interesting finding study no-linearity growth studied additional reinforcement amount. Consistent literature review conducted, which identified take into account different factors failure mode.
