Investigation of GFRP strengthened RC non-slender columns under eccentric loading

Blog Article

An experimental analysis of reinforced-concrete columns was conducted in the paper to evaluate the effectiveness of circular, rectangular and square cross sections strengthened with the glass fibre reinforced polymer (GFRP) when subjected to eccentric loading.Parameters analysed SPEARMINT in the paper are the type of cross section and eccentricity values.It was established that, due to uniform loading, the strength increase of circular sections is greater compared to square and Comics rectangular sections.In addition, the strength and ductility of columns increase with the fibre reinforced polymer wrapping.
