The current study included an experimental examination of the structural behavior of standard wooden beams strengthened in flexure using carbon fiber reinforced polymer (CFRP) sheet, and aimed at determining the effective length and width of the strengthening CFRP sheet. The study included testing of ten standard timber beams using four-point loading method. One of the standard timber beams was non-strengthened and the others were strengthened with CFRP sheets. The strengthened timber beams were divided into three groups depending on the width of the strengthening CFRP sheet. Each group contains three specimens with different lengths for the strengthening CFRP sheet. Experimental results showed that there is a range for the effective length of the strengthening CFRP sheet. Moreover, the research also find out that the increase in sheet width (CFRP area ratio) does not always lead to a consistent improvement in the flexural behavior of the timber beams. Finally, it can be concluded that the CFRP sheet could be more effective in strengthening the timber beam in flexural when the sheet length extends beyond the region of maximum bending moment but not further than the sections with moments lower than half the maximum moment and its width equal to beam width. |
