Results of studies have shown that wrapping of reinforced concrete columns with FRP caused increasing of ductility and compressive strength of RC columns. Since, almost all RC columns are affected by axial force and moment bending. Studies of interaction curve of wrapped RC columns with FRP shows that just compressive control region in interaction curve enhance and wrapping of columns with FRP has no affected on tension control region of RC columns. The objective of this research program is to enhancement flexural strength of RC columns with high and low axial steel content when retrofitted by FRP system that oriented in the direction of applied axial load. one reinforced concrete column designed and modeled under lateral cyclic loading and constant axial load. it is demonstrated analytically that it is possible to strengthen the flexural resistance of RC columns. 000011546 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000011546 653__ $$aFRP, Strengthening, Column,NSM 000011546 7112_ $$a14th World Conference on Earthquake Engineering$$cBejing (CN)$$d2008-10-12 / 2008-10-17$$gWCEE15 000011546 720__ $$aSarafraz, Mehdi$$iDanesh, F. 000011546 8560_ $$ffischerc@itam.cas.cz 000011546 8564_ $$s395484$$uhttps://invenio.itam.cas.cz/record/11546/files/05-02-0006.pdf$$yOriginal version of the author's contribution as presented on CD, Paper ID: 05-02-0006. 000011546 962__ $$r9324 000011546 980__ $$aPAPER
