EXPERIMENTAL STUDY ON ECCENTRIC COMPRESSION SHORT COLUMNS STRENGTHENED BY TEXTILE-REINFORCED CONCRETE ON SIDE

Textile-reinforced concrete has gained increasing popularity due to its favourable properties, namely corrosion resistance, anti-high temperature, better ability in anti-crack, ease and speed application and minimal change in geometry. The eccentric compression experiments of short columns strengthened by TRC on side were conducted under mainly different parameters, specifically in eccentricity, the load history and numbers of fibre sheet layers. The experimental results show that: the method strengthened by TRC on side is suitable for the big eccentricity column and the strengthen effect shows increasingly powerful with eccentricity; load history is harmful to strengthen effect, and the strengthen effect decreases while the load history increases; It is useful to increase strengthen effect by adding fibre sheet layers in some extend, but it shows decreasing trend. Finally, based on the related existing study and test data, the formula of calculating ultimate bearing capacity is proposed, and it shows a satisfactory agreement between the calculated and the experimental results.
