Abstract
This investigation attempts to analyze the flexural behavior of a strengthened beam with carbon fiber sheets in three stages according to the conditions of the constituents : elastic stage, pre-yielding stage, and post-yielding stage. The proposed analytical method for strengthened beams is compared with the experimental results such as yield load, ultimate load, and flexural rigidities. The contributions of the constituents to the strengthened beam capacity are examined from the flexural analysis. The validity of using KCI strength method to estimate ultimate moment of a strengthened beam is also investigated.
