Abstract:
For predicting the development of moments and deflections so as to get a good flexural design, the strip method was used in the force analysis. The ultimate strength theory, the equilibrium and compatibility conditions were adopted, and the moment-curvature and load-deflection relationship were solved using a numerical method, and the computation codes as well as a GUI program were proposed for the solutions. The comparison between theoretical results and experimental results shows that the ultimate strength theory is well applicable to the prediction of flexural strength of concrete beams reinforced with FRP bars, for the calculation of short-term deflections of concrete beams reinforced with FRP bars, the result of ACI model is too small compared to experimental results, the Faza&GangaRao model is more suitable under service loads. The numerical method is more suitable under ultimate loads, and the comparison among these methods indicates that the numerical method is more suitable for the solution of short-term deflections of concrete beams reinforced with FRP bars. 3 tabs, 5 figs, 16 refs.
