摘要: Abstract Inserting FRP rods into grooves using the NSM technique has been demonstrated to be a suitable method for repairing or strengthening RC beams. Recently, availability of GFRP highlighted notwithstanding low elasticity and shear modulus. This paper elaborates considerations on rod basis results experimental investigation pull-out tests concrete specimens with rod, bending non-strengthened beams strengthened and, lastly, through vibration same aforementioned A theoretical bond analysis evaluating strain data stress-slip laws was developed taking account strengthening. The were carried out defining static behaviour until failure. Given that occurrence damage in elements leads change dynamic response, case free–free ends evaluate both rods. Comparison between permits discuss actual assess
