In the present study, numerical analysis of concrete columns wrapped with different composite materials is conducted. Different fibre reinforced plastic sheets such as CFRP, BFRP, HFRP, AFRP, GFRP and steel wrapping are taken into consideration. A cylindrical specimen representing a short column modelled Total deformation, Directional deformation Equivalent stresses in core shell were obtained ...

Abstract Carbon fiber reinforced plastic (CFRP) is extensively used in automotive and aerospace industries with the aim to achieve reduction on emissions by reducing weight. Due governmental regulations reduce environmental impact waste, need for remanufacturing CFRP becoming an interesting area of application economic benefits industry. This important as manufacturing carbon a costly process m...

Strengthening of reinforced concrete beams using externally bonded CFRP laminate is the most popular choice. However, premature end peeling of CFRP laminate has been shown to be the main weakness of this method. Development of high shear and normal stresses at the end of strengthening laminate is the key reason to cause end peeling which is not preventable by conventional anchoring system. This...

This research program is intended to verify the influence of using distributed external U-wrap CFRP anchorage to shift the failure mode from overall debonding to sectional flexural failure for concrete beams externally bonded with CFRP sheets. Premature cover delamination and FRP debonding are predominant failure modes in FRP flexural strengthening that may be delayed or prevented by using FRP ...
