碳纤维布围覆加固T形钢筋混凝土梁受弯承载力试验研究
Experimental Study on Concrete T-Beams Strengthened with Carbon Fiber Reinforced Polymer(CFRP) Sheets on Three Sides
【摘要】 通过对三面围覆碳纤维布进行加固的钢筋混凝土T形梁的试验,探讨了梁的受弯破坏形态、极限状态和设计要求,并根据实测纤维布极限应变值,讨论了纤维布允许拉应变的取值问题。
【Abstract】 In this paper, through test of concrete T-beams strengthened with carbon fiber reinforced polymer (CFRP) sheets on three sides, the failure modes, ultimate flexural limit states and designing demands are discussed. The allowed stress of carbon fiber sheets is also analyzed according to the measured stress.
