Strengthening of short circular columns using FRP materials – determining the effect of confinement

Original language description

This paper is addicted to strengthening of loadbearing reinforced concrete vertical members by composite materials. These modern materials are used more and more in the last years. Using of the FRP fabrics as confinement has several advantages but, there are some questions within the frame of design (such as determining the compressive strength of confined concrete and limit strain of confined concrete). An assessment of influence of the confinement on the members (its load bearing capacity and ductility) is necessary for design. There are a large number of analytical formulas, prescriptive approaches and prescriptions, which specify the resulting influence on the confinement. The paper draws attention to the considerable dispersion between these obtained results. The article presents an analysis of an influence of confinement on reinforced concrete columns, which are wrapped with FRP fabric. The obtained theoretical results were compared with a real behaviour of several samples of confined concrete columns. The short reinforced concrete circular columns were used as the experimental samples. The high to the diameter ratio of the columns was 2:1, thus, an influence of slenderness to loadbearing capacity of the column can be neglected. Therefore, the influence of confinement can be maximized and the dispersion of results according to different methodologies can be emphasized.
