Abstract:	本研究將使用分層(layer-by-layer)斷面彎曲曲率分析方法，模擬FRP筋混凝土梁彎曲與曲率之曲線，藉此了解FRP筋梁之撓曲行為。文中，亦以實驗與模擬結果進行比對。實驗試體共有十一根梁，和其他文獻試體進行模擬分析，藉此比較鋼筋梁與FRP筋梁受撓曲破壞下，其撓曲行為的不同。實驗結果發現，FRP筋滑移問題較普通鋼筋明顯，會影響預測FRP筋梁之彎矩與曲率的準確性。 The target of the research is to study the flexural behavior of FRP reinforced concrete beams by means of sectional analysis and experimental verification. The sectional analysis is made via layer-by-layer method. The experimental work is provided to verify the availability of the traditional section analysis. Eleven reinforced concrete beams reinforced with FRP and steel bars are tested. The predict specimens included test beams by flexural failure in the study and other beams in references. The comparison between tested and predicted results on flexure behavior was made. The results show that the FRP bars slip effect is more obvious than steel bars, which may affect the accuracy of prediction.
