EXPERIMENTAL STUDY ON FLEXURAL BEHAVIOUR OF TIMBER BEAMS REINFORCED WITH BFRP SHEETS

BFRP sheet is a new type of complex material with outstanding performance. According to the static tests of 12 rectangular timber beams strengthened with basalt fiber reinforced polymer(BFRP) sheets,it is analyzed that the performance indexes such as the bearing capacity,deflection of reference beams and reinforced beams. The results show that BFRP sheets have a good strengthening effect for timber beam. Finally,the ANSYS software is applied to the numerical stimulation of the bending test of the timber beam reinforced by BFRP sheets. Then,the load-displacement curve and stress-strain nephogram of reinforced timber beam under vertical load are gained. Through the comparison of numerical result and experimental result,it verifies that using ANSYS software to the numerical stimulation of BFRP reinforced timber beam is feasible.
